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.

|---|---|
| Peak | 42 in (3 ft 6 in) |
| Vestibules | 9 sq ft + 9 sq ft |

| Packed weight | 68 oz (4 lb 4 oz) |
| Packed volume | 8.6 L |
| Regular pads that fit | 2 with an inch to every wall |
| Sit-up room on a pad, at the peak | +6 in for 35 in sitting height |
| Pitched footprint | 86 × 104.4 in (7 ft 2 in × 8 ft 8 in), floor and vestibules |
| Groundsheet to cut | About 84 × 50/40 in |
On the campsite
Floor and vestibules together cover 86 × 104.4 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 84 × 50/40 in.
Notes
Floor 86 × 52/42 in, 42 in head height, two doors with 9 ft² side vestibules. Big Agnes lists the floor area only (28 ft²); the dimensions are REI’s.

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.
