How to Buy a Tent

This part's easy. You've basically got four options

Size
Manufacturers build tents for very specific end-uses and always put their recommendation of maximum capacity on the tent specs. These are numbers you can trust. But think about details like how many people on the average will be sleeping in the ten and whether you want a tight fit to save on weight or might like plenty of room?

With car camping, err on the larger side (a little space can go a long way—especially when it comes to family camping). For backcountry, we also suggest upgrading by one size; some one-person tents weigh a pound less, but we favor a bit more weight to have a lot more room.

Most companies have visual footprints (with dummy campers sleeping in mummy bags) to give you a real sense of space. Also pay attention to the floor dimensions to make sure you have enough space to stretch out.

The max ceiling height indicates the apex of the tent interior. Chances are you won't be buying a tent you can stand up in (unless you go with a "base camp" cabana-style tent). But unless you like adopting pilates positions to get in and out of your sleeping bag, look for a tent that has enough head and elbow space to move around and space to change clothes, etc.

Tent Care
For something that's almost always exposed to the elements, keeping yours in pristine condition isn't as hard as you might think. First, consider buying a ground tarp. These serve double duty: they protect your tent floor (one of the most vulnerable parts of the tent) and offer additional protection in wet conditions. Most companies make them specific to the actual tent, so they marry perfectly get one that's too big and water and dirt can get funneled into your tent You can make one yourself by cutting standard tarp to the exact dimensions of your tent's footprint. Also, when pitching the tent, aim for shade if possible; long exposure to sun will deteriorate the fabric.

When you get home, re-pitch your tent and give it a quick wipe with a wet wash cloth or sponge. If things got really muddy, you can hand-wash it in the tub with warm water or soup (or consider one of the many different outdoor-specific cleaning products). And even if you don't clean your tent thoroughly, always be sure it's fully dry before you pack it away, unless you crave the scent of mildew and the patina of mold.
