What to Pack for a Week

Updated August 2026 · Vacation Checklists

A week fits in a carry-on for most people, most trips. The reason it works is arithmetic: 5 tops and 3 bottoms in colors that all go together produce 15 outfits from 8 garments, which is more than you need for 7 days, and those 8 garments take up about a third of a standard carry-on. Add underwear and socks for the week, one layer, one pair of shoes beyond the ones you're wearing, a quart bag of liquids, and your electronics, and you're done.

The people who need a checked bag for a week usually don't need it because of the week. They need it because of a formal event, ski gear, or small children. Everyone else is packing for a fear, not for a schedule.

Updated August 2026. Liquid rules referenced here are TSA rules at US checkpoints and apply to carry-on bags. Bag size and weight limits are set by each airline and vary, so check your carrier's own page. Confirm current security rules at tsa.gov before you fly.

Traveling for two or three nights instead? That's a different and much smaller problem, and it's covered in our weekend trip packing list. This page is about the 7-day version.

The Outfit Math: 8 Garments, 15 Outfits

Here's the entire trick, written out.

Take 5 tops and 3 bottoms. If every top works with every bottom, that's:

5 x 3 = 15 distinct outfits from 8 pieces of clothing.

For a 7-day trip, you need 7 outfits. You have 15. You have more than double what the trip requires, and you're carrying 8 items.

Now compare it to the way most people pack, which is one outfit per day chosen as a complete look: 7 tops and 7 bottoms, 14 garments, producing exactly 7 outfits because the pieces weren't chosen to mix. Nearly twice the volume for less than half the flexibility.

What makes the multiplication actually work: color discipline. Pick one neutral base (black, navy, gray, tan, olive) for all 3 bottoms, then choose tops that all work against that base. Two or three tops can be your accent colors. If a top only works with one specific pair of pants, it isn't part of the capsule, it's a passenger.

Two more rules that keep the math honest:

• Every piece has to survive being folded in a bag. Anything that needs pressing after a flight is out.
• One layer, chosen to go over everything. A cardigan, an overshirt, or a light jacket in the base neutral covers cold planes, cool evenings, and slightly dressier dinners.

A worked example: 7 days in Lisbon in May

Highs around 72F, lows around 55F, a decent chance of rain, a lot of walking on hills, and one dinner out.

Capsule: 3 t-shirts, 1 linen button-down, 1 nicer knit top (5 tops). Dark jeans, olive chinos, a navy skirt or shorts (3 bottoms). All bottoms neutral, all tops work against all three. 15 outfits.

Everything else: 8 underwear, 5 pairs of socks, sleepwear, a packable rain shell, a light cardigan, walking shoes (worn) plus one pair of flats or loafers, quart bag, chargers, a small day bag.

Packed volume:

A 22 x 14 x 9 inch carry-on is about 45 liters gross and roughly 35 usable once you subtract wheels, the handle housing, and the shape of the bag. 26.5 liters into 35 usable leaves genuine room for what you buy there. That's the whole point of packing this way: not deprivation, but slack.

What to Pack for a Week: The Full 7-Day Checklist

Work down this list. Counts are for one adult, 7 days, temperate weather. The trip-type section below tells you what to swap.

Clothing

• [ ] 5 tops (mix of casual and one dressier)
• [ ] 3 bottoms, all in the same neutral family
• [ ] 1 layer: cardigan, overshirt, or light jacket
• [ ] 1 packable rain shell

• [ ] 5 pairs of socks (fewer if you're in sandals)
• [ ] 1 set of sleepwear
• [ ] 1 swimsuit if there's any water at all
• [ ] 1 outfit that works for a nice dinner, assembled from pieces already on the list

Footwear

• [ ] 1 pair of comfortable walking shoes (worn on travel day)
• [ ] 1 second pair that covers a different use: dressier, sandals, or trail
• [ ] Optional third pair only if you have a specific, confirmed need

Toiletries (quart bag for carry-on)

• [ ] Toothbrush, toothpaste
• [ ] Solid or travel-size shampoo, conditioner, body wash
• [ ] Deodorant (solid stick, not a liquid or gel, so it stays out of the quart bag)

• [ ] Pain reliever, antihistamine, anti-diarrheal, motion sickness tablets
• [ ] Adhesive bandages and blister patches
• [ ] Hand sanitizer

Documents and money

• [ ] ID or passport
• [ ] Boarding passes and hotel confirmations, saved offline
• [ ] 2 payment cards, stored in different places
• [ ] Some local cash
• [ ] Insurance details and one emergency contact written down

Electronics

• [ ] Phone, charger, cable
• [ ] Power bank
• [ ] Headphones
• [ ] Plug adapter and, if needed, a voltage-appropriate converter
• [ ] Laptop or tablet only if you'll actually use it

Power bank rules, current as of the ICAO update dated 27 March 2026: spare power banks are carry-on only, two spares maximum, and they must be accessible at your seat rather than in the overhead bin. No in-flight charging of or from a power bank. Under 100Wh needs no approval, 100 to 160Wh requires airline approval in advance, and over 160Wh is not allowed on passenger aircraft. Most travel banks (10,000 to 27,000 mAh) fall between roughly 37 and 100Wh. The Wh figure is printed on the case, and individual airlines apply these rules differently, so check your carrier's page too.

Laundry and organization

• [ ] Laundry bag or a spare tote for dirty clothes
• [ ] Travel detergent: sheets, a solid bar, or a few single-use packets
• [ ] Universal sink stopper (a flat rubber disc, one of the cheapest things you can pack)
• [ ] Braided travel clothesline or a few clips
• [ ] 2 or 3 packing cubes
• [ ] A day bag that folds flat

Deliberately not on this list: a hair dryer, full-size anything, a book you won't finish, a third pair of jeans, "just in case" outfits with no assigned use, and a second bag for the things that didn't fit in the first.

Laundry Is the Lever That Makes a Week Fit

One mid-trip sink wash cuts your clothing count by about a third. That's the difference between 8 garments and 12, or between a carry-on and a checked bag.

You are not doing laundry for the fun of it. You're doing about 15 minutes of work on day 4 to avoid carrying 5 extra liters for 7 days.

What a sink wash actually takes:

1. Fill the sink or tub with warm water. Use the universal stopper if the hotel's is missing or leaks, which it usually is or does.
2. Add a detergent sheet or a squeeze of the bar. A small amount. Too much soap is the main reason things don't rinse clean.
3. Agitate for two minutes, then let it sit for ten.
4. Rinse until the water runs clear.
5. Roll each item in a dry bath towel and press hard. This step is the whole difference between dry by morning and damp by morning. It removes far more water than wringing does, and it doesn't stretch the fabric.
6. Hang on the clothesline, over the shower rail, or on hangers. Point the room's air conditioning at it if you can.

Dry times, roughly, in a normal hotel room overnight:

Which is a good argument for choosing merino and synthetic pieces for the capsule in the first place, and for never planning to wash jeans mid-trip.

When to use a real laundromat instead: trips over 10 days, family trips with kids, or anywhere you're generating gym or hiking clothes daily. A wash and fold service in most cities runs a modest per-pound fee and comes back the next day. On a 7-day trip you rarely need it. On a 14-day trip, one visit replaces an entire second bag.

Adjustments by Trip Type

The 5 x 3 capsule is the skeleton. Here's what changes.

Business trips are the one type where the capsule gets tighter, not looser. Dress shirts and one suit or blazer in a neutral means every shirt works with every combination. Wear the blazer and the dress shoes on the plane, since they're the heaviest and most crush-prone items you own.

Beach trips need two swimsuits so one is always dry, and that's the only genuine duplicate on the whole list. The rest of a beach week is lighter than a city week, not heavier.

Cold-weather weeks are where the volume fights back. Wear the coat and the boots on the plane, pick a compressible puffer over a wool overcoat, and use merino base layers you can re-wear all week.

The Honest Limit: When One Carry-On Doesn't Work

Not every week fits a carry-on, and pretending otherwise is how people end up gate-checking a bursting bag at the last minute.

Check a bag when:

• There's a formal event. A suit, a gown, or a dress uniform that can't be crushed is a garment bag's job. One wedding turns a carry-on trip into a checked trip, and that's fine.
• You're bringing ski, dive, camping, or golf gear. Boots, a wetsuit, a sleeping bag, or clubs are simply too large. Rent at the destination if you can.
• You're traveling with small children. Diapers, a car seat, a stroller, and multiple changes per day per child do not fit in your bag on top of yours. Family travel is a checked bag problem and always has been.
• You need liquids over 3.4 oz. Specialty products, a full-size sunscreen for a beach week, or anything you can't buy at the destination.
• You're taking gifts, or coming back with them. An empty checked bag on the way out is a legitimate strategy for a trip where you'll return heavy.
• Medical equipment. A CPAP, a nebulizer, or supplies for a condition come first, and everything else works around them. Note that many airlines and the TSA treat assistive medical devices as additional to your normal allowance, so ask your airline directly.
• Your airline's carry-on rules are tight. Weight limits in particular are stricter on many non-US carriers than most travelers expect.

Two practical notes. First, if you'll be at the edge, check your bag against your airline's published limits with our carry-on size checker rather than trusting the label on the suitcase. Second, on Southwest, the published carry-on maximum is 24 x 16 x 10 inches, which is more generous than most, but the airline does not publish a personal item dimension, so plan around the under-seat space rather than a number someone quoted you online. As of 2 May 2026, Spirit Airlines has ceased all operations, so ignore any older size chart that includes it.

Frequently Asked Questions

How many outfits do I need for a week?

Seven days of wear, which the 5 x 3 capsule delivers with 15 possible combinations from 8 garments. You don't need 7 planned looks, you need enough mix-and-match pieces that nothing repeats in a way you'd notice. Add one dressier top and you've covered a nice dinner too.

How many pairs of underwear for a week?

Seven to eight, one per day plus a spare. This is the one category where packing extra costs almost nothing in volume, so don't get clever with it. Socks are more flexible: five pairs is plenty if you're in sandals part of the time, and seven if you're walking all day in closed shoes.

Can I really do 7 days in a carry-on?

Yes, for most trips and most people. The Lisbon example above comes to 26.5 liters in a bag with 35 usable liters. What defeats it is bulky items (a wool coat, a second pair of boots), full-size liquids, and sports gear, not the number of days. Days are cheap; volume is expensive.

Should I roll or fold for a week-long trip?

Roll knits, t-shirts, jeans, and underwear, since rolling saves space and reduces crease lines. Fold structured items like dress shirts, blazers, and anything with a collar, and use a packing folder if you have one. Most efficient packers do both, then use cubes to keep the rolled layer from unrolling itself when you open the bag.

How do I pack for a week when the weather changes mid-trip?

Layer rather than pack two wardrobes. Base layers plus the same 5 tops plus a packable insulating layer plus a shell handles a surprisingly wide range. Keep all bottoms neutral so nothing depends on a specific pairing, and accept that one or two days will be slightly less ideal than they would be with a dedicated outfit.

What's the difference between packing for a week and packing for a weekend?

Almost nothing, structurally. A weekend needs 2 to 3 outfits and no laundry plan; a week needs the capsule and one mid-trip wash. The toiletries, documents, and electronics categories are identical for both. The short-trip version, with the smaller counts, is in our weekend trip packing list.

How much should a week's carry-on weigh?

Aim for 15 to 20 lbs packed. Under 15 lbs is easy to lift into an overhead bin and comfortable to carry through a station. Over 25 lbs, you'll feel it on every set of stairs, and you're at risk on airlines that enforce a carry-on weight limit, which many international carriers do at 15 to 22 lbs.

Should I bring travel detergent or use hotel laundry?

Bring detergent sheets. They weigh almost nothing, cost very little for a whole pack, and give you the option without committing to it. Hotel laundry services are priced per item and are usually the most expensive way to wash a t-shirt anywhere in the world. A laundromat or a wash and fold shop sits in between and makes sense from about day 10.
