Best Pergola for a Small Patio
The 10' x 12' pergola fits a 14' x 14' clear space in the sizing page's worked example (rotated to run its 12' side into the depth); the 12' x 16' pergola does not fit that same space in either orientation.
The smaller footprint, confirmed against the manufacturer's own figures
10' x 12', against the 12' x 16' larger pergola in the same range - both by the manufacturer's own stated roof size, cross-checked against Creators API itemDimensions where published. See the sizing page's worked example: against a 14' x 14' clear space, the 10' x 12' pergola fits (rotated so its 12' side runs into the 14' depth); the 12' x 16' pergola does not fit that space in any orientation, since its 16' side exceeds 14' either way.
The caveat that applies either way
This is a roof-footprint check, not a floor-space guarantee - neither pergola publishes the distance between its own support posts, which is always somewhat smaller than the roof. See pergola roof size vs. usable space before assuming the full roof footprint is usable floor, and measure the actual installation location rather than relying on the 14' x 14' example above, which is illustrative only.
What the smaller pergola doesn't give up
Not durability - both pergolas share the same 72 mph wind rating, per the manufacturer. The 10' x 12' pergola is actually the only one of the two with a published snow-load rating (6 in accumulation, 55 lb per square meter); the larger pergola's own listing doesn't state one. See 10' x 12' vs. 12' x 16' " louvered pergola for the full side-by-side.
Who it suits, and who should look elsewhere
Suits a tighter patio or side yard where the 12' x 16' footprint wouldn't clear. Buyers with a larger space, or who want the stated 192 sq ft coverage and two independently adjustable roof sections, should look at the 12' x 16' pergola instead.
