Overpacking is the most common travel mistake — bags get heavier, fees appear, and half the contents come home unworn. A packing list built from the trip's length, climate and purpose solves the problem before the suitcase does.
Length drives the core
Short trips need few items; long trips need a plan, not a bigger bag. Underwear and socks scale roughly one per day, while tops and trousers plateau because they can be worn again and washed. This is why a 14-day trip needs far fewer than double a 7-day trip's clothes.
Climate and trip type layer on top
Warm climates add swimwear and sunscreen; cold ones add layers, hat and gloves; business adds smart outfits. By combining both dimensions, the list reflects the trip you're actually taking rather than a generic template.
Packing smart beats packing more
Mix-and-match clothes, rolling instead of folding, and planning a laundry stop on longer trips let you pack less and lose nothing. The list gives you the items; these habits keep the bag manageable.
Frequently asked questions
As a rule of thumb: one day's underwear and socks, plus 3–5 tops, 2 pairs of trousers and a layer for evenings. This calculator tailors exact quantities to your trip.
Both. The climate sets the basics (layers, jacket, warmth), while the trip type adds the specifics — swimwear for the beach, smart outfits for business.
Stick to one colour scheme, pack clothes you can mix and match, plan for laundry on long trips, and only bring items you'll genuinely use.
