Quick answer: A good holiday packing list starts with the trip, not the wardrobe. Work out the nights, the weather and the dress code, then build a capsule around them: tops, bottoms, one layer, nightwear, swimwear if needed, and a toiletry bag. Sort each category into its own packing cube and you will pack faster and forget less.

What this guide covers

I plan holidays the way I used to plan a school trip: a register, a headcount, and a firm belief that if it can be forgotten, someone will forget it. Three kids and a good number of years of caravan parks, ferries and long-haul flights to Dhaka have taught me that a holiday packing list is not about cramming in more. It is about deciding, at the kitchen table with a cup of tea, exactly what each trip needs before a single sock goes in the case.

The mistake most of us make is packing for the wardrobe we own rather than the days we are about to live. A city break and a beach fortnight are different animals. So here is my honest, trip-by-trip system, the one I actually use, with the contingencies built in because something always goes sideways.

Start with four questions, then pack

Before anything, answer these. How many nights. What is the weather doing. Is there a dress code, a wedding, a fancy dinner. And what will you be doing all day, walking or lounging. Those four answers decide the whole list, and they stop you packing five going-out tops for a trip that is really wellies and rain.

Once you have the answers, build a small capsule: two or three bottoms, four or five tops that all go together, one warm layer, nightwear, and whatever the trip demands on top. A packing cube set turns that capsule into a system, one category per cube, so you can see the whole trip at a glance.

How much to pack by trip type

Here is the cheat sheet I keep in my head. It is a starting point, not a rule, and you trim from here.

Trip typeNightsCubesThe extras that matter
City break2-32 small, carry-onComfy shoes, one smart outfit, brolly
Beach holiday7-103-4 plus a wet bagSwimwear x2, sun cream, after-sun
Ski or winter5-7Compression cubesBase layers, thick socks, gloves
Backpacking14+3 plus a laundry cubeQuick-dry kit, first-aid, dry bag
Family holiday71 cube per personSnacks, spare clothes, the calm bag

Notice the beach and ski rows. A beach week is mostly light, floppy, forgiving stuff, so standard cubes are perfect. A ski week is bulky base layers and jumpers, which is exactly where a compression cube earns its place, and I explain the real space maths in the compression cubes guide.

The short-trip list: two nights, carry-on only

City breaks are where cubes shine, because you are fitting a whole trip under a seat. Two small cubes do it: one for tops and underwear, one for a spare bottom and nightwear. Wear the bulkiest items on the plane. Check your airline's hand luggage rules before you pack, because a bag that fits easyJet may not fit Ryanair, and nothing sours a Friday like a gate fee. My carry-on packing guide has the full week-in-a-cabin-bag method if you want to push it further.

The beach and long-haul list: a full week away

This is the trip that tempts everyone to overpack, so I am strict here. Five tops, three bottoms, two swimsuits, one cover-up, one evening outfit, and sandals plus trainers. That covers a fortnight if the tops mix and match, and it genuinely does. Roll the light stuff into a core packing cube, keep swimwear in its own cube so the damp never touches your dry clothes, and pack a separate wet bag for the journey home.

The unglamorous hero of the long trip is the toiletry bag. A hanging wash bag that opens on the back of a hotel door saves you spreading bottles across a shared bathroom shelf, which, with children, is the difference between calm and chaos. For a full week or a multi-country trip, the nine-piece cube set gives everyone their own colour and still fits one case.

The family list: one cube each, no exceptions

Families need a different logic, and I have written the whole system in the family packing guide. The short version: one cube per child, a different colour each, and you never dig through a shared case at bedtime again. Pack a "calm bag" in your hand luggage too, with snacks, wipes, a spare outfit and something quiet to do, because the delay always comes and it always comes at the worst time.

The things every list forgets

Whatever the trip, these are the four I have learned to write down every time: a plug adaptor, any medication in your hand luggage not the hold, a copy of your documents, and one full spare outfit within reach. Check the Foreign travel advice for your destination while you are at it, because entry rules and health notes change, and it takes two minutes. Which? has sensible, independent testing if you are still choosing a suitcase to put all this in.

The truth of packing well is not owning more. It is deciding less, once, calmly, before you start. Build the capsule for the trip in front of you, give every category its own cube, and you will arrive with what you need and none of the low hum of "did I forget something" that ruins the first evening. Browse the full packing cubes range and pick the set that matches your next trip.

Frequently asked questions

How do I write a holiday packing list I will actually stick to?

Start with the trip, not your wardrobe. Answer four questions first: how many nights, the weather, the dress code, and what you will do each day. Build a small mix-and-match capsule from those answers, then sort it into one packing cube per category so nothing is forgotten.

How many packing cubes do I need for a family holiday?

The simplest system is one cube per person, each a different colour, so everyone can find their own clothes without unpacking the whole case. For a week away, a set of six to nine cubes covers a family of four comfortably in a single large suitcase.

What always gets forgotten on a packing list?

The usual four are a travel plug adaptor, medication in your hand luggage rather than the hold, a copy of your travel documents, and one complete spare outfit kept within reach for delays or lost bags. Write these down first, before the clothes.
