10 Essential Packing Tips Every Traveler Should Know

I once watched a woman at the check-in counter in Hanoi break down in tears because her suitcase was 8 kilograms over the Vietnam Airlines weight limit and the excess baggage fee cost more than her flight. I have been that woman, minus the tears, at a Ryanair gate in Bergamo, Italy, where I paid 60 euros to check a bag that I could have carried on if I had packed differently. Over seven years and roughly forty trips, I have refined my packing system to the point where I can pack for two weeks in a single backpack in under twenty minutes. These are the ten principles that made that possible.

"The world is a book and those who do not travel read only one page." — Saint Augustine

Tip 1: Choose the Right Bag and Stick With It

This single most important packing decision you will make is not what goes inside the bag but which bag you choose. After trying rolling suitcases, duffel bags, and backpacks of every size and brand, I settled on the Peak Design Travel Backpack 30L, and I have used it exclusively for three years. It meets the carry-on size limits of every major airline I have encountered, including budget carriers like Ryanair (55 x 40 x 20 cm) and EasyJet (56 x 45 x 25 cm). It opens clamshell-style like a suitcase, which makes packing and unpacking far easier than top-loading backpacks. It has external access pockets for my laptop and passport, compression straps that reduce the bag volume by 30 percent when it is not full, and a luggage pass-through sleeve for attaching it to a rolling suitcase on the rare occasions I check one.

If you prefer a rolling suitcase, the Away Carry-On (68 x 45 x 25.5 cm) is the most popular option for good reason: it is durable, has a built-in USB charger, and comes with a lifetime warranty. The Samsonite Winfield 2 is a solid budget alternative at about half the price. For a hybrid option, the Osprey Farpoint 40 is technically a backpack but has a Use that zips away, allowing it to be carried like a duffel. It is the bag I used on my first five solo trips, and it held up admirably across four continents before I switched to the Peak Design for its clamshell opening.

A reason choosing one bag and committing to it matters is that it forces discipline. When you know exactly how much space you have, you naturally edit down to what fits. The mistake most people make is choosing a bag that is slightly too large, which creates room for the "just in case" items that never get used. A 30-to-40-liter bag is the sweet spot for trips up to two weeks. Anything larger, and you will fill it. Anything smaller, and you will spend the trip wishing you had more space. Find your bag, learn its dimensions, and refuse to upgrade.

Tip 2: The Five-Day Rule for Clothing

Here is the rule that transformed my packing: if you would not wear an item at least five times during your trip, it does not go in the bag. This single criterion eliminates the "maybe I will need this" items that account for most overpacking. On a two-week trip to Japan, my clothing list was four tops, two bottoms, seven pairs of underwear, one set of sleepwear, and one outer layer. That is it. I wore each top roughly three to four times, which is easy when you choose versatile, neutral-colored pieces that can be mixed and matched. A black merino wool t-shirt from Uniqlo (25 USD) works under a blazer for a nice dinner, with jeans for daytime exploring, and with athletic shorts for sleeping.

One fabric you choose matters more than the quantity. Merino wool is the gold standard for travel clothing because it is naturally odor-resistant, moisture-wicking, temperature-regulating, and quick-drying. I have worn the same Uniqlo merino t-shirt for three consecutive days in hot, humid climates without it smelling. Icebreaker makes excellent merino base layers, though at 80 to 100 USD per piece, they are an investment. For budget options, Uniqlo AIRism line performs almost as well at a fraction of the price. For bottoms, I wear Prana Stretch Zion pants (89 USD), which are lightweight, quick-drying, have a hidden zip pocket for valuables, and look presentable enough for restaurants. They also convert to capris with a zipper at the knee, effectively giving me two styles in one garment.

Laundry is the enabler that makes minimal packing possible. I hand-wash clothes every three to four days using a 2-ounce bottle of Dr. Bronner Pure-Castile Liquid Soap (3 USD), which works for clothing, body, hair, and even dishes in a pinch. Merino wool and synthetic fabrics dry overnight when hung on a towel rack or shower curtain rod. Cotton, which retains moisture and dries slowly, is the enemy of carry-on travel. I have eliminated cotton from my travel wardrobe entirely, replacing it with merino wool, linen (for hot climates), and synthetic blends. The result is a packing list that weighs under 3 kilograms for two weeks of clothing.

Tip 3: Use Packing Cubes Religiously

Packing cubes are not optional; they are the organizational backbone of a well-packed bag. I use two Peak Design packing cubes (one large, one medium) that compress clothing by about 40 percent using an internal compression zipper. The large cube holds tops and underwear; the medium cube holds bottoms and my outer layer. Each cube has a mesh panel so I can see what is inside without opening it, and a grab handle for pulling it out of the backpack without disturbing the rest of the contents. The entire process of unpacking in a hotel room takes about 90 seconds: unzip the backpack, pull out the two cubes, place them in a drawer or on a shelf, and I am done.

If Peak Design cubes are outside your budget, the Amazon Basics four-piece set (15 USD) works well enough. The key feature to look for is compression: cubes without compression zippers save space compared to loose packing, but cubes with compression zippers save significantly more. I also use a small Eagle Creek cube (12 USD) for toiletries, which keeps liquids contained in case of spills and has a hook for hanging in the bathroom. A single spill from a shampoo bottle can ruin an entire packing job; the toiletry cube is insurance against that.

The packing method I use inside the cubes is rolling, not folding. Rolling clothes into tight cylinders minimizes wrinkles, maximizes space efficiency, and makes it easy to see and access individual items without unpacking the entire cube. I roll each item separately, place the largest items at the bottom of the cube, and layer smaller items on top. Socks get rolled and tucked into the corners and gaps. Underwear goes into a small mesh pouch inside the large cube. This system sounds fussy, but once you do it a few times, it becomes automatic, and the time saved during the trip, no digging through a disorganized bag, more than compensates for the ten extra minutes of packing.

Tip 4: Build a Universal Toiletry Kit

My toiletry kit is a permanent, pre-packed kit that lives in my closet ready to go. I never unpack it between trips; I just restock consumables. The kit itself is a Sea to Summit Travelling Light Hanging Toiletry Bag (35 USD), which has a hook for hanging, multiple compartments, and a waterproof lining. Inside, I keep travel-sized containers of everything I need, all compliant with the TSA 3-1-1 rule for carry-ons: liquids in containers of 3.4 ounces (100 ml) or less, all fitting in a single quart-sized clear bag.

The specific products in my kit, which I have refined over years of travel: CeraVe hydrating facial cleanser (travel size, 6 USD), Supergoop Unseen Sunscreen SPF 40 (travel size, 14 USD), Dr. Bronner liquid soap (2-ounce bottle, 3 USD), Lush solid shampoo bar (11 USD, lasts about 30 washes and counts as a solid, not a liquid), Tom's of Maine deodorant (solid stick, no liquid restriction), a bamboo toothbrush, and a travel tube of Sensodyne toothpaste. For medications, I carry a small pill organizer with ibuprofen, antihistamines, Pepto-Bismol tablets, and any prescription medications in their original bottles. I also include a compact microfiber towel from Sea to Summit (22 USD) that packs to the size of a grapefruit and dries in about an hour.

The one item I never travel without is solid sunscreen. Liquid sunscreen counts toward your liquid allowance and is prone to exploding in pressurized cabins. A solid sunscreen stick, like the ones from Sun Bum (10 USD) or Green Goo (12 USD), takes up zero liquid allowance space, cannot spill, and applies easily. I also switched to a solid perfume from Meow Meow Tweet (18 USD) after a bottle of liquid cologne shattered in my bag during a turbulent flight from Bangkok to Chiang Mai, destroying a silk scarf and a paperback novel. Solids are simply more travel-proof than liquids, and I have converted as many toiletry items as possible to solid form.

Tip 5: The Electronics Essentials

My electronics kit has been stripped down to four items: phone, Kindle Paperwhite, Anker PowerCore 10000 portable charger, and a single USB-C cable that charges both my phone and my Kindle. That is it. I used to travel with a laptop, a camera, a separate e-reader, noise-canceling headphones, and a tangle of cables. On a trip to Vietnam, my laptop was stolen from a hostel locker, and I spent three days dealing with police reports and insurance claims instead of enjoying Hoi An. When I replaced the laptop, I decided not to bring it on future trips, and I have never missed it. My phone handles email, navigation, translation, photos, and journaling. The Kindle handles reading. The portable charger handles battery anxiety.

The Anker PowerCore 10000 (26 USD) is the best portable charger for travel because it is small enough to fit in a pocket, weighs 180 grams, and holds enough charge to fully recharge a phone two to three times. I charge it every night along with my phone, and I top up my phone from it during the day while exploring. This system means I never run out of battery, which is critical when your phone is your map, translator, payment method, and camera. I also carry a single USB-C to USB-C cable (Anker PowerLine II, 12 USD) that is braided nylon and has survived being bent, stepped on, and stuffed into bags for over two years without fraying.

For power adapters, I use the Epicka Universal Power Adapter (25 USD), which has four USB-A ports, one USB-C port, and works in over 150 countries. It replaces the collection of country-specific adapters I used to carry and lets me charge all my devices from a single outlet. One consideration: check the voltage compatibility of your devices before plugging them in. Most modern phone chargers and laptop adapters are dual-voltage (100-240V) and work worldwide, but older or cheaper devices may only support 110V. Using a 110V device in a 220V country without a voltage converter will fry it. The Epicka adapter does not convert voltage; it only adapts the plug shape. If you have a voltage-sensitive device, you need a separate converter like the BESTEK Universal Travel Adapter (35 USD).

Tip 6: Shoes: The Two-Pair Maximum

Shoes are the heaviest items in most travelers bags, and the most overpacked. My rule is two pairs maximum: one on my feet, one in my bag. The pair on my feet during travel is my primary walking shoe, which needs to be comfortable enough for 15,000 to 20,000 steps per day, durable enough for varied terrain, and presentable enough for casual dinners. After years of trying different options, I wear Allbirds Wool Runners (98 USD) for travel days and general walking. They weigh 320 grams each, are machine washable, and the merino wool upper resists odor even after consecutive days of wear. I have walked 25,000 steps in them through Tokyo without a single blister.

The pair in my bag depends on the destination. For warm-weather trips, I pack Xero Shoes Z-Trail sandals (60 USD), which weigh 227 grams each, have a toe strap for hiking security, and can be worn in water. For cold-weather trips, I pack a pair of thin wool socks from Smartwool (20 USD) and wear my Blundstone Thermal Series boots (230 USD) on travel days instead of the Allbirds. For hiking-focused trips, I wear Merrell Moab 3 Ventilator hiking shoes (115 USD) on travel days and pack a pair of lightweight canvas sneakers like the Converse Chuck Taylor (55 USD) for evenings.

Key principle is that both pairs must serve a distinct purpose, and both must be broken in before the trip. I never travel with new shoes. Blisters on the second day of a trip can affect your entire experience, limiting how far you can walk and what you can do. I wear my travel shoes for at least two weeks before departure, including one full day of walking equivalent to what I expect on the trip. If they cause any discomfort during the test period, they stay home and I choose a different pair. Your feet are your primary mode of transportation when you travel; investing in the right shoes and breaking them in properly is the single most impactful packing decision you can make.

Tip 7: The Document Organizer That Saves Hours

I keep all my travel documents in a Bellroy Travel Wallet (90 USD), which has dedicated slots for my passport, boarding passes, SIM cards, currency, and cards. Before I started using a dedicated travel wallet, I once spent twenty minutes at a check-in counter in Bangkok digging through my backpack for my printed visa approval letter while a line of irritated travelers formed behind me. The travel wallet eliminates that kind of chaos by keeping everything in one place that I can access in seconds.

Inside the wallet, I carry: my passport (with at least six months validity), two photocopies of my passport (one in the wallet, one in a separate bag), two passport photos (for visas on arrival), printed copies of all accommodation bookings and flight confirmations, my travel insurance card with the policy number and emergency phone number, a debit card with no foreign transaction fees (I use the Charles Schwab debit card, which reimburses all ATM fees worldwide), a credit card with no foreign transaction fees (Chase Sapphire Preferred), and 200 USD in emergency cash split between the wallet and a hidden pocket in my daypack.

I also carry a laminated card with emergency contact information: the phone numbers for my bank (international collect line), my travel insurance emergency line, the nearest embassy or consulate for my destination, and the contact information for a friend or family member back home who has a copy of my full itinerary. This card has come in handy twice: once when my wallet was stolen in Barcelona and I needed to call my bank immediately, and once when I was in a minor scooter accident in Bali and the hospital needed my insurance information. Having everything in one place, organized and accessible, reduces stress in situations that are already stressful enough.

Tip 8: The Personal Item Strategy

Most airlines allow one carry-on bag and one personal item, and maximizing the personal item is the most underused packing hack in travel. Your personal item should be a small backpack or tote bag that fits under the seat in front of you and holds everything you need during the flight plus a day's worth of essentials in case your carry-on is lost or gate-checked. I use the Peak Design Everyday Zip 20L (150 USD), which has a dedicated laptop sleeve, a water bottle pocket, and enough room for my electronics, documents, a change of clothes, and my toiletry kit. It slides easily under the seat and doubles as my daypack for the entire trip.

What goes in the personal item: passport and travel wallet (in an external pocket for easy access at security), phone and portable charger, noise-isolating earbuds (I use the 1MORE Triple Guide in-ear monitors, 100 USD, which sound better than headphones twice the price and take up a fraction of the space), a reusable water bottle (Nalgene 32 oz, 11 USD, empty through security and filled at the gate), a neck pillow (the Trtl Wrap, 30 USD, which is a fleece wrap with internal plastic supports, not an inflatable pillow, and takes up almost no space), and a packed change of clothes including underwear. This last item is critical: if your checked bag is delayed, you have a clean outfit to change into while you wait.

The personal item strategy also works as a weight-distribution system. Budget airlines like Ryanair and EasyJet enforce carry-on weight limits strictly (10 kg for Ryanair, no limit but must fit in the sizer for EasyJet). By putting heavy items like electronics, documents, and a water bottle in your personal item, you reduce the weight of your carry-on bag. On a Ryanair flight from Bergamo to Lisbon, I was 0.5 kg over the limit with everything in my carry-on. I moved my Kindle, portable charger, and a guidebook into my personal item, and the carry-on weighed in at 9.7 kg. It is a small adjustment that can save you a 60-euro gate-check fee.

Tip 9: The "Wear Your Heaviest" Principle

The simplest and most effective weight-saving strategy is to wear your heaviest and bulkiest items on the plane. This means your largest shoes, your heaviest outer layer, and your bulkiest pants all go on your body, not in your bag. On a winter trip to Japan, I wore my Blundstone boots (770 grams each), my Patagonia Down Sweater jacket (370 grams), and my heaviest jeans on the flight. In my bag, I packed lightweight merino layers, a packable rain jacket, and thinner pants. This single strategy reduced my bag weight by roughly 2.5 kilograms, which is the difference between a comfortable carry-on and an overweight bag that requires checking.

This principle extends beyond clothing. If you are traveling with a heavy item like a laptop, camera, or guidebook, carry it in your personal item rather than your carry-on. Wear your bulkiest jewelry instead of packing it. If you are bringing a winter coat, wear it through the airport even if it is warm; you can always take it off and stuff it in the overhead bin once you are seated. The airport is not a fashion show, and no one cares if you are wearing hiking boots and a winter coat in July. They care even less once you are on the plane and they cannot see you at all.

One caveat: wear your travel outfit for at least a few hours before the flight to make sure it is comfortable for sitting. Tight jeans, stiff boots, or a heavy jacket that restricts movement will make a long-haul flight miserable. My standard travel outfit is Allbirds Wool Runners, Prana Stretch Zion pants (which have a gusseted crotch for comfort), a merino t-shirt, and a lightweight zip-up hoodie. This outfit weighs about 1.5 kilograms, is comfortable for 12+ hours in a plane seat, and looks presentable enough that I can go directly from the airport to a restaurant or hotel without changing.

Tip 10: The Pre-Packed Emergency Kit

The last item in my bag is a small zip-lock bag that I call my emergency kit, and it contains ten things that have saved me repeatedly over the years. First, a mini roll of toilet paper (you will understand the first time you encounter a squat toilet with no paper). Second, five individually wrapped wet wipes (for cleaning hands, surfaces, or yourself after messy street food). Third, a small tube of antibiotic ointment and five Band-Aid brand adhesive bandages (for blisters, cuts, and scrapes). Fourth, a single Imodium tablet in its original blister pack (for the inevitable traveler's stomach issues). Fifth, two safety pins (for wardrobe malfunctions, broken zippers, or makeshift clotheslines).

Sixth, a small lighter (for sealing the ends of cut ropes, lighting candles during power outages, or sterilizing needles). Seventh, a 2-meter length of paracord (for makeshift clotheslines, securing bags, or replacing broken straps). Eighth, a small carabiner (for attaching things to your daypack, hanging bags in hostel lockers, or clipping wet clothes to a line). Ninth, a single dental floss pick (because flossing with a full pack of floss is impractical in hostel bathrooms). Tenth, a 10,000-yen note or a 20-dollar bill taped to the inside of the zip-lock bag as emergency currency that is separate from your wallet. This stash is for the moment when you lose everything else: your wallet, your phone, your cards. Having even a small amount of hidden cash can get you a meal, a bus ride, or a phone call to your embassy.

This entire kit weighs less than 200 grams and takes up less space than a paperback novel. I assemble it once and keep it packed between trips, replacing consumables as needed. It has come to my rescue in situations ranging from a burst pipe in a Lisbon guesthouse (wet wipes and toilet paper) to a broken sandal strap on a Greek island (safety pin and paracord) to a three-day bout of food poisoning in India (Imodium and wet wipes). You will hopefully never need most of these items, but when you do need one, you will be grateful it is there. The emergency kit is not about pessimism; it is about the kind of self-reliance that makes travel less stressful and more enjoyable.
