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.

The numbers
| Floor (listed) | 118 × 100 in, 81.9 sq ft |
|---|---|
| Peak | 80 in (6 ft 8 in) |
| Vestibules | None |
| Sleeps (maker) | 6 |
| Packed weight | 257 oz (16 lb 1 oz) |
| Packed volume | 56.2 L |
| Regular pads that fit | 5 with an inch to every wall |
| Sit-up room on a pad, at the peak | +44 in for 35 in sitting height |
| Standing room | 51.8 sq ft at 5 ft 9 in, 60.9 sq ft at 5 ft 3.5 in |
| Pitched footprint | 118 × 100 in (9 ft 10 in × 8 ft 4 in), floor and vestibules |
| Groundsheet to cut | About 116 × 98 in |
On the campsite
Floor and vestibules together cover 118 × 100 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 116 × 98 in.
Notes
Floor 118 × 100 in, 80 in peak, no vestibule (one is sold separately).
