Which pads fit
Tight, 0.5 in from the wall. Sit-up room +2.1 in.
They don't fit side by side: 4.1 in past the wall.
An inch or more to every wall. Sit-up room +2.1 in.
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.
Where 3 wide pads fit instead
The lightest 3-person backpacking tents where they fit with an inch to every wall.

The numbers
| Floor (listed) | 88 × 66/60 in, 38.5 sq ft |
|---|---|
| Peak | 42 in (3 ft 6 in) |
| Vestibules | 8 sq ft + 8 sq ft |
| Sleeps (maker) | 3 |
| Packed weight | 47 oz (2 lb 15 oz) |
| Packed volume | 7.4 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 |

| Groundsheet to cut | About 86 × 64/58 in |
On the campsite
Floor and vestibules together cover 88 × 112.2 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 86 × 64/58 in.
Notes
Floor 88 × 66/60 in (REI; Big Agnes lists only 38 ft²), 42 in peak, a door and an 8 ft² vestibule on each side. Semi-freestanding.

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.
