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) | 92 × 90 in, 57.5 sq ft |
|---|---|
| Peak | 70 in (5 ft 10 in) |
| Vestibules | None |
| Sleeps (maker) | 4 |
| Packed weight | 201 oz (12 lb 9 oz) |
| Packed volume | 47.7 L |
| Regular pads that fit | 4 with an inch to every wall |
| Sit-up room on a pad, at the peak | +34 in for 35 in sitting height |
| Standing room | 12.6 sq ft at 5 ft 9 in, 30.8 sq ft at 5 ft 3.5 in |
| Pitched footprint | 92 × 90 in (7 ft 8 in × 7 ft 6 in), floor and vestibules |
| Groundsheet to cut | About 90 × 88 in |
On the campsite
Floor and vestibules together cover 92 × 90 in. On a square tent pad, as campgrounds list them: 8 × 8 ft: fits; 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 90 × 88 in.
Notes
Floor 92 × 90 in, 70 in peak and near-vertical walls; no vestibule, so gear rides inside.

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.
