Start with this decision
Start with the limiting resource for the trip: water for dry camping, propane for cold nights, food for groups, or battery runtime for off-grid stays.

FAQ
Common questions
Which camping calculator should I use first?
Start with food, water, ice, fuel, or power because those are the supplies most likely to cause problems.
Should I round camping estimates up?
Yes. Weather, appetite, delays, and activity level can all increase real needs.
Are these tools for tent camping or RV camping?
Both. Some focus on tents and backpacking, while others support RV, camper, and campground planning.
Do I need extra water?
Usually yes. Heat, pets, cooking, cleanup, illness, and delays can all increase water needs.
Can I use these offline?
Once loaded, many static pages can remain usable in the browser, but do not depend on that as your only plan.
