How to Pack a Suitcase Efficiently: Methods, Rules and Mistakes to Avoid

Checked on 18 October 2026. Security and airline rules change. The liquids and battery rules below come from GOV.UK and the Civil Aviation Authority; check your departure airport and airline before you travel.

Start with a list, then cut it

Efficient packing starts before you open the case. Lay out everything you think you need, then remove anything you would not miss for the length of the trip. Three questions help:

• Will I use this more than once? If not, can something else do the same job?
• Can I buy it there? Sun cream, toiletries and adaptors are often cheaper at your destination than in the airport.
• Does it go with at least two other things? Clothes that only work with one outfit take up space for one day's wear.

Plan around a single colour family so tops, bottoms and shoes all mix. Wear your bulkiest shoes and jacket on the journey rather than packing them. A packable waterproof folds into its own pocket and fills a gap; our guide to waterproof ratings explains what the numbers on the label mean.

The order that makes everything fit

For a wheeled suitcase, pack in layers, starting at the wheel end so the case stays balanced when it stands upright.

Fill gaps as you go. A case packed tightly creases less than a half-empty one, because clothes cannot slide around.

Roll or fold?

There is no single best method. Each works better for different clothes.

Bundle wrapping means laying long items flat in a star shape and wrapping them around a soft core, such as a pouch of underwear. The curve stops sharp creases forming. Most people combine all three: fold the smart clothes, roll the casual ones and use the rolls to fill gaps.

The 5-4-3-2-1 and 3-3-3 rules

Both are rules of thumb for packing less. They are not official rules, and different travel writers give slightly different versions.

• 5-4-3-2-1: five tops and four bottoms. Three pairs of shoes, including the pair you wear. Two swimsuits or accessories, and one hat. It suits a week-long beach or summer holiday.
• 3-3-3: three tops, three bottoms and three pairs of shoes, chosen so that every top works with every bottom. That gives nine outfits, and it suits city breaks and shorter trips.

For longer trips, plan to wash clothes rather than packing more. A week's worth of clothes can last a month if you can use a launderette or a hotel laundry.

Packing for one week or one month

• One week: follow 5-4-3-2-1 or 3-3-3, and you can often fit everything in a large cabin bag. See our guide to cabin bag allowances on Ryanair and easyJet before you decide whether to pay for a hold bag.
• Two weeks to a month: pack for about a week and plan one or two washes. Add a small travel wash or laundry sheets and a few clothes pegs.

Shoes

Shoes are the bulkiest thing most people pack. Limit them to two pairs in the case and wear the third.

• Stuff socks, chargers or small items inside them so the space is not wasted.
• Put each pair in a shoe bag or a carrier bag to keep dirt off your clothes.
• Pack them heel to toe along the wheel end or the sides of the case.

Suits and smart clothes

To pack a suit jacket, turn one shoulder inside out. Tuck the other shoulder into it. Then fold the jacket once along its length. Lay it flat in the middle layer, with trousers folded along their creases underneath. Hang everything up as soon as you arrive. A steamy bathroom helps light creases drop out.

How packing cubes help, and when they do not

Packing cubes are zipped fabric pouches that group clothes by type or by day. They do not create space on their own, but they make a case easier to organise and keep tidy when you live out of it. Compression cubes have an extra zip that squeezes out air, which helps with bulky soft items.

• They help: on multi-stop trips, for families sharing a case, and with a backpack or soft bag.
• They help less: on short trips with a well-planned case, where they add weight and corners that waste space.

Compressing clothes reduces their volume, not their weight, so check your airline's weight limit if you compress a lot.

Liquids and toiletries

At most UK airports you still cannot take containers of liquid larger than 100ml through security in your hand luggage, and some airports ask for them in a single clear bag of about 20cm by 20cm, according to GOV.UK's hand luggage rules. Some airports allow containers up to 2 litres, so check every airport you depart from, including on the way home. Our UK airport liquids rules guide has the limit at each major airport.

• Medicines, special dietary liquids and baby food or milk are allowed in containers up to 2 litres at all UK airports.
• In a checked bag, seal liquid bottles in a zip bag and pack them in the middle of the case, surrounded by clothes.
• Solid shampoo, conditioner and deodorant avoid the liquids rules altogether.

What must go in your hand luggage

The Civil Aviation Authority's Pack Right guidance is clear that some items must travel in the cabin, where crew can deal with a fire.

• Power banks, spare batteries and vapes: in your hand luggage only. Never in a checked bag. The CAA limit is two power banks per person, and they should not be recharged on board.
• Larger batteries: batteries of 100 to 160 watt-hours need airline approval, and anything over 160Wh is not allowed in passenger baggage.
• Laptops, tablets and phones: carry these in the cabin unless they are fully switched off and protected. If your cabin bag is taken to the hold at the gate, take batteries and devices out first.

Keep medicines, documents, keys and valuables with you too. A delayed or lost checked bag is far easier to cope with if these are in your hand luggage. Our British guide to travel insurance explains what cover usually applies to delayed and lost bags.

The five biggest packing mistakes

• Packing for every possible situation. Pack for the trip you have planned and buy anything you genuinely need there.
• Leaving it to the last minute. Packing in a rush leads to overpacking and forgotten essentials. Start a list a few days before.
• Putting essentials in the hold. Medicines, chargers, a change of clothes and travel documents belong in your hand luggage.
• Ignoring weight until the airport. Weigh the case at home with a luggage scale; airline excess fees at the desk are usually far higher than buying extra allowance online.
• Filling the case completely. Leave about 10% of the space for anything you bring home.

• Weigh and measure the case against your booking.
• Shoes and heavy items at the wheel end.
• Smart clothes folded flat in the middle, casual clothes rolled into the gaps.
• Liquids in containers of 100ml or less, in one clear bag, unless your airport says otherwise.
• Power banks, spare batteries and vapes in your hand luggage.
• Medicines, documents and a change of clothes in your hand luggage.
• Space left for the journey home.
