Checking a bag for a beach trip is optional. A full week at the beach — including everything you actually need, minus nothing you'll actually use — fits in a standard carry-on (22" × 14" × 9") plus a personal item. This guide gives you the exact system and the complete packing list.
The Core Principle: Wear More, Pack Less
The biggest carry-on mistake is packing outfit options instead of a system. Options create packing inefficiency — the "just in case" dress that takes up half a bag and gets worn once, or the third pair of shorts that you packed because you might want a choice.
A system is different: every piece works with every other piece, nothing is single-use, and the math of combinations gives you more outfits than items packed.
The Clothing System for a Week Beach Trip
Tops (4 pieces):
- 1 Oversized tee (light color) — beach cover-up, travel layer, casual day shirt. Worn 3-4x during the week.
- 1 Pocket tee (neutral color) — the day shirt for non-beach days, layering piece. Worn 2-3x.
- 1 Crewneck sweatshirt — worn on the flight both ways, cool evenings, overly air-conditioned restaurants. Worn 3-4x.
- 1 Slightly elevated tee or linen shirt — for one nicer dinner or evening. Worn 1-2x.
Bottoms (3 pieces):
- 1 Swim short/swimwear — under the tee for beach days, alone at the pool.
- 1 Chino or linen short — for non-beach day activities and elevated casual situations.
- 1 Versatile trouser or jean — for evenings, travel days, and any cooler days. Worn on the plane to save bag space.
The math:
4 tops × 3 bottoms = 12 outfit combinations from 7 pieces. Add the crewneck as a layer and you have more options than a week requires.
The Beach Kit
- 1 premium beach towel — If the hotel provides towels, skip this. If not, our lounge towel rolls tight enough to fit in the side pocket of most carry-ons. Call the hotel before deciding.
- 1 hat — Wear it through security. It takes up zero bag space this way.
- 1 tote bag — Packs flat. Becomes the beach bag. Also functions as your personal item on the plane if you load it right.
Shoes (3 pairs max)
Wear your bulkiest shoes on the plane.
- Casual sneakers or loafers (worn on the plane)
- Slides or sandals (flat, pack easily)
- Optional: one pair of nicer sandals or loafers if your itinerary includes elevated situations
Three pairs of shoes in a carry-on requires strategic packing: shoes go heel-to-toe in a separate packing cube, against the back panel of the bag. This is non-negotiable for making everything else fit.
Toiletries: TSA-Compliant System
The 3-1-1 rule (3.4oz containers, 1 quart-sized bag, 1 bag per person) is workable with the right containers and a willingness to buy sunscreen at your destination.
What to put in travel containers:
- Shampoo and conditioner
- Face wash
- Moisturizer/SPF face lotion
- Toothpaste
What to buy at your destination:
- Full-size sunscreen (over 3oz, not worth the travel bottle)
- Any other large liquids
Buying sunscreen locally saves significant bag space and baggage-claim time, and costs the same or close to the same as your home sunscreen.
The Packing Order (This Matters)
- Shoes — heel-to-toe against the back panel
- Heavy items (toiletry bag, electronics) — next to shoes, low in the bag
- Rolled clothing — fill the center space
- Flat items (beach towel rolled, hat brim up) — against the front panel or top
- Personal item (tote) — everything you'll want during the flight, nothing that you won't need until you land

Frequently Asked Questions
What size carry-on do I need for a week beach trip?
A standard 22" × 14" × 9" carry-on (the maximum allowed by most US carriers) plus a personal item. With the system above, a week beach trip fits comfortably. If you're flying budget carriers with tighter restrictions, the personal item becomes critical — pack your most essential daily items there in case the carry-on must be checked.
Do I really need to buy sunscreen at my destination?
Yes. At typical beach trip sunscreen usage (4+ oz per day, reapplied every two hours), you need more sunscreen than you can carry through TSA in 3oz containers. Buying at your destination takes 10 minutes and costs the same as bringing it. The bag space and security-line ease is worth it every time.
Can I pack a beach towel in a carry-on?
Yes, if it's a good one. A premium cotton beach towel rolled tightly fits in the side pocket or top of most 22" carry-ons. A cheaper, thicker towel may not compress enough to be worth bringing. Call the hotel first — most beach properties provide towels and the question resolves itself.
