Pads side by side at their listed sizes, with the average man (5 ft 9 in) lying on each. "Tight" is under an inch to a wall or the sloping roof: the fabric gives, but a wet wall wets what touches it. Open it in TentCheck to try your own pads, cots and gear, or read how fits are checked.

On the campsite

Floor and vestibules together cover 120 × 102 in. On a square tent pad, as campgrounds list them: 8 × 8 ft: doesn't fit; 10 × 10 ft: fits; 12 × 12 ft: fits. Guylines and stakes need more room around that.

For a groundsheet, cut it a little smaller than the floor, about 2 in, so rain running off the fly doesn't collect on it and run under the tent: about 118 × 100 in.

Notes

Floor 120 × 102 in (10 ft × 8 ft 6 in), 72 in center height, one wide door and no vestibule. Coleman says its nearly vertical walls give 20% more headroom than its traditional domes.

Roof shapes are modeled from the floor, the peak and how the poles hold the walls, not measured. Treat a result within an inch or two as too close to call.
