Clothing Quantity for Trip by Days

Clothing by trip length

Start from 1 outfit per day + 1 to 2 spares in case something gets stained, you get caught in the rain, or plans change. A 7-day trip works out to 8–9 sets. For 14 days, don't keep scaling up linearly; cap it around 9–10 and plan to do laundry. Past a certain point you're packing for laundry, not for duration, and you can count on washing every 5–7 days no matter how long you're gone, since hotels, hostels and Airbnbs almost always have a washer or a paid service. The capsule wardrobe idea (Project 333: 33 items for 3 months) leans on this by keeping everything mix-and-match in 2–3 colors. One more thing to watch is the airline limit. Carry-on 7–10 kg is the Brazilian standard (Latam, Gol, Azul), and checked 23 kg applies to international economy. Low-cost carriers (Ryanair, EasyJet, Wizz) are tighter, sometimes 1 piece up to 7 kg.

Applications

Backpacking out of one 40 L pack, business trips (a suit plus 2–3 shirts), long-stay rentals of a month or more, beach holidays, ski trips, and squeezing into a low-cost carrier's carry-on rules.

FAQ

What if the trip is longer than 14 days? Stop at 7 outfits and plan to wash. After the second week, packing for laundry wins over packing for the whole stretch.

How do socks and underwear scale? Figure 1 pair per day up to about 7–10, then rely on laundry. They weigh almost nothing and dry overnight.

Should I include the travel day outfit? Yes. What you wear to the airport counts as 1 set, because you'll want a change once you arrive.
