Backpack or suitcase for Thailand? The short answer: if your itinerary includes Bangkok, the north, and the islands, a 40 to 60-litre travel backpack is your best bet — it fits into tuk-tuks, night buses, and boats without ever slowing you down. A suitcase only makes sense for a laid-back stay with one or two bases. Between beaches, jungles, and lively cities, this guide helps you choose the right luggage and pack it smartly: complete checklist, rainy season, and documents not to forget.
One principle above all: travel light. Thailand is the easiest country to do laundry (laundries are everywhere and cost just a few bahts) and to buy anything you might need. Half of the travellers leave with a bag that's too heavy and a third of it unopened. Here are the three bags we recommend, one for each type of traveller.
Our Selection for Thailand
Three profiles, three bags. The island and rainy season traveller needs a waterproof bag to protect belongings on a longtail boat or under a tropical downpour. The northern trekker (Chiang Mai, Pai) opts for a lightweight bag for hours of carrying. Those settling in Bangkok or Phuket seek organisation. You can also browse our collection of waterproof backpacks — the number one criterion in these latitudes.
Backpack or Suitcase: The Right Choice for Your Itinerary
The backpack remains the most versatile option for Thailand. It slips through Bangkok's alleys, fits between songthaew seats, and is easily carried on island piers where wheels won't survive. For a classic two to three-week circuit, a capacity of 40 to 60 litres is more than enough; beyond that, you're carrying excess. Check three things: padded straps and hip belt, multiple access compartments, and a ventilated back — Thai humidity is unforgiving.
The wheeled suitcase has its fans, and it has merits: clothes stay pristine, organisation is simpler, and in Bangkok, Chiang Mai, or Phuket hotels, it poses no problem. It becomes a burden when the itinerary involves multiple transfers — broken pavements, station steps, pier sand. Simple rule: more than three different accommodations, take the backpack; one or two bases, the suitcase works.
Final adjustment: cabin size. For a two to three-week light trip, a cabin-sized bag (55 × 40 × 20 cm) avoids checked baggage fees on low-cost domestic flights — Air Asia, Nok Air, and Thai Lion charge separately for checked luggage and weigh bags. If you plan to take multiple domestic flights, this criterion alone can decide the bag. For more details, our guide on what's prohibited in cabin luggage will save you from surprises at security.
What to Pack: The Thailand Checklist
The climate decides for you: hot and humid all year, between 28 and 35 °C. Lightweight, breathable fabrics (cotton, linen) are essential, and everything dries quickly — allowing for a reduced luggage. Here's the tried-and-tested essentials:
- Clothing: 5-6 lightweight t-shirts, 2 shorts, 1 lightweight trousers, 2 swimsuits, underwear for a week — no more, laundries do the rest.
- For temples: an outfit covering shoulders and knees (light trousers or sarong) — mandatory at the Grand Palace and most wats.
- Footwear: sandals that come off easily (you'll remove them everywhere: temples, homes, some shops) + a lightweight closed pair for treks.
- Pharmacy: anti-diarrhoea, rehydration, tropical mosquito repellent (dengue present), sunscreen — the rest can be bought at local pharmacies.
- Electronics: universal adapter (plugs A, B, and C), power bank for long journeys, waterproof phone case.
- Miscellaneous: headlamp, earplugs (guesthouses can be noisy), small padlock for hostel lockers.
All the extras can be found locally, often cheaper than in the UK: the ubiquitous 7-Elevens are handy at any hour, and markets sell t-shirts and sarongs for a few pounds. If in doubt about an item, leave it: it's the golden rule of successful packing, detailed in our guide on how to prepare your travel bag.
The Monsoon Changes Everything: Think Waterproof
From June to October, the monsoon drenches the country with brief but spectacular showers — and the rest of the year, a longtail crossing is enough to soak a bag left at the boat's bottom. It's the classic Thailand travel trap: you think "sun", you discover "deluge". A main bag with coated fabric or roll-top closure protects the essentials; failing that, a rain cover for the entire bag does the job for a few grams.
For day trips — waterfalls, snorkelling, floating markets — a small waterproof daypack is the most useful travel accessory. Folded, it weighs nothing in the main luggage; unfolded, it protects your camera, passport, and dry clothes on a kayak or under a downpour. It's typically the item you don't bring on the first trip and never leave behind on the second.

Documents and Security: The Essentials
Regarding documents: passport valid for 6 months after return date, outbound ticket (required at boarding), and from 2025 the digital arrival card to be completed online before the flight. As rules regularly change (visa exemption duration, requirements), check the latest conditions on the French government's Thailand travel advice page a few weeks before departure. Keep a photo of your passport on your phone and a paper copy stored separately.
Thailand is a safe country, but pickpockets love night markets and Bangkok's tourist areas as much as anywhere else. Good habits: never put your passport and money in an outer pocket, split cash into two places, and protect your bank cards from skimming — an RFID-blocking sleeve weighs ten grams and solves the problem. In dorms and hostel lockers, a small padlock from our collection of travel padlocks completes the kit.
Organising the Inside: The Move That Changes the Trip
A Thai circuit means packing and unpacking your bag every two or three days. Without organisation, the bag becomes a bottomless pit by the first week. The proven solution: packing cubes — one for tops, one for bottoms, one for dirty laundry — transferred from one accommodation to another without unpacking. Add a compression bag for bulky clothes and you gain the equivalent of a third of your luggage.
One last field tip: always keep 20% empty space at departure. Between clothes bought at markets, souvenirs, and crafts, the bag inevitably swells during the trip — and excess baggage fees on domestic flights are costly. A slightly underfilled bag at the start, well-organised and rain-protected: that's the formula for successful packing for Thailand. Safe travels — and if you're still hesitating between models, our complete collection of travel bags covers all profiles.
