Quick answer: Two 64 cm wide sleeping pads require at least 128 cm of usable floor width where both sleepers' shoulders and hips rest, plus some clearance at the tent walls. A “2-person” label does not prove that two wide pads fit. Measure the actual inner floor and compare the shape of both inflated pads before ordering.
Start with the pad dimensions you can verify
Both the Light Tour R4.2 and Light Tour R7.5 list three inflated sizes:
- R: 178 × 55 × 10 cm, pictured with a tapered outline.
- RW: 186 × 64 × 10 cm, pictured with rounded corners.
- L: 196 × 64 × 10 cm, pictured as a fuller rectangular outline.
The shape matters. A tapered R pad may leave more room at the foot end than a rectangular L pad even when the shoulder widths are close. Also check headroom: an inflated pad lifts your sleeping bag around 10 cm from the floor, bringing it closer to sloping inner walls.
Do the two-person width math before you buy
| Two-pad combination | Combined maximum listed width | What to check |
|---|---|---|
| R + R | 110 cm | Usable floor width at shoulders, hips, and foot end. |
| R + RW or L | 119 cm | Whether the wider pad can sit away from the sloping wall. |
| RW/L + RW/L | 128 cm | Wall clearance in addition to the 128 cm sum; test the actual pad outlines. |
These totals are simple width sums, not confirmed fit ratings. In particular, 128 cm of nominal floor width leaves no allowance for bathtub walls, fabric slope, or the gap you may want between sleepers. A narrow spot at the foot end can also prevent two full-length wide pads from lying flat.
A five-minute tent-fit check
- Find the current inner-floor plan for your exact tent and inner option, not the fly or footprint dimensions.
- Measure floor width where both shoulders and hips will lie, and measure again toward the feet.
- Compare both pad outlines at those points. Add a small practical margin for bathtub walls and sleeping-bag loft.
- Check usable length and sloping-wall clearance after allowing for the pad's inflated height.
- If dimensions are close, lay out cardboard or paper templates at home before a trip.
This method applies to the Lanshan 2, Floating Cloud 2, and Taiji 2. Their designs and inner options differ, so do not transfer a fit claim from one model to another. For a solo shelter such as the Lanshan 1, measure the 64 cm wide pad against the usable inner width and the slope above your shoulders; “1P” alone does not establish comfort with an RW or L pad.
Best for
Couples choosing two pads for a compact 2P backpacking tent; solo campers considering an RW or L pad; Lanshan, Floating Cloud, and Taiji owners who want to avoid a floor-plan surprise.
Not ideal for
Using tent capacity as a precise width measurement; putting a pad under a wet fly or against an inner wall because it technically fits; assuming two 64 cm pads will fit every two-person tent.
FAQ
“Can I put two 25-inch pads in a Lanshan 2?”
Two 64 cm pads are about 25.2 inches each, so their maximum widths sum to 128 cm. Check the current Lanshan 2 inner-floor measurements and the two pad shapes before treating that as a yes.
“Does choosing R4.2 instead of R7.5 solve a space problem?”
No. The two product listings show the same three inflated size choices. Change pad size or shelter layout; choose R-value for insulation.
“If the pads fit on the floor, is the setup comfortable?”
Not necessarily. Check clearance from the sloped walls and whether both sleepers can turn without pushing the inner into the outer fly.
“Which guide should I read next?”
Use the width and side-sleeping guide to select a pad size, the R4.2 vs R7.5 comparison to select insulation, and the R-value guide to understand what the number means.
