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.

On the campsite

Floor and vestibules together cover 98 × 96.8 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 88 × 30 in.

Notes

90 × 32 in floor on trekking poles with an 11 ft² vestibule beside each door. Durston lists a 45 in peak; as on the other X-Mids, the inner is modeled 5 in lower (40 in). The weight is the Dyneema-floor typical setup.

Sources

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.
