About this tool
Build and tick off a beach packing list sized by trip length, heat, laundry access and sun hours, with the sunscreen volume worked out.
This builder sizes a beach packing list from four numbers — trip length, laundry interval, daytime high and hours in the sun — instead of handing you a generic checklist. Garment counts come from the laundry-cycle rule (you never need more than one wash cycle plus a day of turnaround), and the sunscreen figure comes from the 2 mg/cm² dermatology dose, about 30 ml to cover an adult body, reapplied every two hours. It also weighs the result against your cabin or checked allowance and audits the liquids against the 100 ml container and 1 litre bag limits.

Every line has a quantity derived from your days, heat and laundry access.
Uses the full 2 mg/cm² dose, which is roughly four times what most people actually apply.
Compares the list against your baggage allowance and against the cabin one-bag liquid rule.
About 30 ml per full-body application, so one adult spending four hours a day in the sun for seven days needs roughly 420 ml — two applications a day at the two-hourly reapplication interval. Most holidaymakers apply about a quarter of the recommended dose, which is why a single 100 ml bottle rarely lasts a trip.
Only as many as one laundry cycle needs. With a wash every four days you are dressing for five days, not ten, so five or six tops covers it; with no laundry at all you need the full ten. The builder applies that rule to every garment automatically.
Each container must hold 100 ml or less and all of them must fit inside one transparent resealable bag of up to 1 litre, one bag per passenger — the standard rule at TSA, EU and Indian (BCAS) security. Larger bottles have to go in checked baggage or be bought after security.
Two at minimum, so one can dry while the other is worn — swimwear packed damp is the usual cause of a musty bag. Add a third if you swim more than twice a day or the humidity keeps things from drying overnight.
