This free trip outfit combination planner counts real outfit combinations from your tops, bottoms and shoes. Enter your trip length and your clothing counts, and the tool shows how many distinct outfits you truly have, so you see if your wardrobe covers every day or falls short.
Most travellers overestimate their wardrobe, because they count pieces instead of combinations. Five tops and three bottoms feel like eight outfits, but the real number is fifteen, since each top pairs with each bottom. Counting combinations instead of pieces is the difference between a bag that works and a bag full of clothes you cannot combine.
To use the tool, enter your numbers in the fields above and press the calculate button. The results table updates at once, and you can change any number and calculate again as often as you like. Everything runs in your browser, so nothing you enter is sent to a server, and you need no account and no sign-up.
The formula multiplies tops by bottoms for outfits, then multiplies again by shoe pairs for full combinations. Days covered is the smaller of full combinations and trip days, and spare combinations are the rest. Shoes count as a multiplier only when they truly change the outfit, so a second pair in the same colour adds less than a pair in a different style.
Example: for a 10 day trip with 5 tops, 3 bottoms and 2 pairs of shoes, the tool gives 15 outfits, 30 full combinations, covering all 10 days with 20 spares. Even if you rule out a few combinations you dislike, the wardrobe still covers the trip twice over.
Tip: remove combinations you would never wear. If a top clashes with a bottom, cross that pair out of the count, because a theoretical outfit you hate is not an outfit, and the honest count is what keeps you from packing too little.
Tip: let shoes do the work of a whole extra outfit. A smart pair of shoes dresses up the same top and trousers for dinner, while trainers keep them casual for day trips, so two shoe styles can double a small wardrobe.
Tip: photograph your favourite combinations before you pack. A phone album of five or six go-to outfits stops morning decisions in the hotel, and it proves the combinations work before you leave home.
Common question: Do shoes really double my outfits? Only if the shoe styles differ enough to change the look. Two similar trainers add almost nothing, while one casual pair and one smart pair genuinely double most combinations, so count shoe styles, not just shoe pairs.
Common question: How many combinations do I need for a week? Aim for at least twice the trip days, so a 7 day trip wants 14 or more combinations. That buffer covers combinations you reject, bad weather changes, and one outfit that gets stained.
Common question: What if my combinations fall short of my trip days? Add one top, not one bottom, because tops multiply against every bottom you already own. One extra top on a 3 bottom wardrobe adds 3 outfits at once, which is the cheapest fix in packing maths.
Packing well is a skill that pays off on every trip. A bag that is planned before you leave saves time at the hotel, avoids overweight fees at the airport, and leaves room for the things you bring home. Spend ten minutes with a plan and the whole trip feels calmer, from the first morning to the last evening.
This tool is free to use as often as you like. Bookmark it, run it before every trip, and let it carry the counting while you focus on the journey itself, the places you will see, and the people you will meet along the way.
