Camping Calculators & Gear Tools
Three free tools for the decisions that are hardest to make by reading alone: how big a tent your family really needs, how long a canister of fuel lasts, and which of two products is the better buy. No signup, no email — enter your numbers and go.
Camping Tent Size Calculator
Enter how many campers, kids, dogs and what sleep system you use — get the floor area, the capacity class you actually fit, and real tents that match. Built for family car camping, not backpacking math.
Prefer the longer read? See the tent size guide with real floor dimensions the calculator is based on.
Propane Burn-Time Calculator
Enter your canister or tank size and your stove's BTU rating — get burn hours, how many meals that covers, and the cost per 100,000 BTU. The fastest way to decide between a 1 lb bottle, a 20 lb tank, or butane.
Prefer the longer read? See the propane vs butane vs isobutane fuel guide the calculator is based on.
Side-by-Side Gear Comparison
Pick any two products from the catalog and put price, star rating, pros and cons in one table — useful when the shortlists are close and the deciding difference is small.

Which Tool Do I Need?
- Buying a tent for a family trip? Start with the tent size calculator, then check the what size tent for 2 adults, 2 kids and a dog walkthrough if you are between two sizes.
- Not sure whether to carry a 1 lb bottle or a 20 lb tank? Run the propane calculator, then compare the two options by cost in the 1 lb vs 20 lb tank cost per trip breakdown.
- Planning meals for a group? The propane calculator answers how much propane you need for camping by trip length instead of guesswork.
- Choosing between a cot, an air mattress and a pad? There is no calculator for comfort, so use the cot vs air mattress vs sleeping pad comparison instead.
How We Keep These Tools Honest
Every calculator here uses published manufacturer specifications — canister net weight, stove BTU ratings, tent floor dimensions — and the product picks read prices directly from our catalog, so a price change on the site shows up in the result. If a number looks wrong, tell us and we will correct it.
