Most packing advice online is written for an imagined average trip, which means it either over-packs you for a short city break or leaves you short for a week of hiking in variable weather. The three things that actually determine what belongs in a suitcase are how many days you're away, what the climate will be like, and what kind of trip it is — a beach holiday and a business trip of the same length need almost entirely different contents. This generator builds its list from exactly those three inputs, rather than handing you one list for every kind of traveller.
Clothing quantities are capped at a sensible outfit count rather than scaling one-to-one with trip length — nobody genuinely needs 14 separate tops for a 14-day trip if laundry is an option, so the list tops out at a week's worth of outfit variety and expects a wash partway through longer trips. Underwear and socks are the exception, calculated with a small buffer above the day count, since these are the items most travellers regret under-packing and cheapest to simply bring enough of.
Climate and trip type solve different problems, so the tool treats them as separate layers rather than folding them together. Climate determines the physical demands on your clothing — will you need to manage heat and sun, or cold and wind, or both within the same trip if you're travelling somewhere with unpredictable weather. Trip type determines the equipment and specialised items a particular activity calls for: a laptop and a spare formal outfit for business, a headlamp and first-aid basics for a hiking trip, goggles and thermal layers for winter sports. Combining both layers means a "cold-climate hiking trip" and a "cold-climate business trip" produce genuinely different lists, which a single one-size list never could.
Documents and tech accessories are the categories travellers most often remember at the airport rather than at home — a universal power adapter, a spare phone charger, printed booking confirmations as backup to a phone that might run out of battery. This generator lists them every time regardless of climate or trip type, since they matter on every single trip and are exactly the sort of unglamorous item that's easy to leave off a list built from memory.
Each item includes a checkbox so you can tick items off directly on this page as you pack them into your bag, which is a faster workflow than retyping the list into a notes app. If your destination has a firm checked-baggage weight limit, cross-reference the finished list against the Luggage Weight Calculator once you start actually filling the suitcase, so you find out you're over the limit at home rather than at the check-in counter.
A final practical note: pack your checked bag with a rough sense of what you'll need first at your destination near the top or in an easily accessible section, rather than packing purely by category. Arriving after a long flight and needing to dig through an entire suitcase just to find a phone charger is a small but avoidable frustration.
Yes for tops — clothing quantities cap around a week's worth of variety on the assumption you'll do a wash partway through longer trips, rather than packing a fresh outfit for every single day.
Choose 'Mixed / unpredictable' climate, which adds layerable items and a compact rain jacket suited to shifting conditions rather than betting on one type of weather.
Generate the list for whichever type dominates the trip, then manually add the handful of extra items — like one formal outfit — the secondary purpose needs.
Toiletries are flagged as needing to be travel-size for carry-on, but exact liquid limits vary by country and airline, so check your specific airline's current carry-on rules before packing liquids.
