They don't fit side by side: 2.5 in past the wall.
An inch or more to every wall. Sit-up room +7.8 in.
Tight, against the sloping wall. Sit-up room +5.2 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.

The numbers
| Floor (listed) | 90 × 45 in, 28.1 sq ft |
|---|---|
| Peak | 48 in (4 ft) |
| Vestibules | 9.3 sq ft + 9.3 sq ft |
| Sleeps (maker) | 2 |
| Packed weight | 17.8 oz (1 lb 1.8 oz) |
| Packed volume | 3.5 L |
| Regular pads that fit | 2 with an inch to every wall |
| Sit-up room on a pad, at the peak | +12 in for 35 in sitting height |
| Pitched footprint | 96 × 93 in (8 ft × 7 ft 9 in), floor and vestibules |
| Groundsheet to cut | About 88 × 43 in |
On the campsite
Floor and vestibules together cover 96 × 93 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 88 × 43 in.
Notes
Floor 90 × 45 in, 48 in peak, single wall on two trekking poles. Zpacks lists each vestibule 24 in deep at the pole but no area; 9.3 ft² is the beak as drawn from its listed dimensions. The ends slope low, so heads and feet go toward the middle.

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.
