10×12 or 12×16
A 10×12 covers 120 square feet and fits a dining set for six exactly. A 12×16 covers 192 and leaves room to walk behind a pushed-back chair. The second difference is the sides: curtains that drape against six screens that close.
Side by side
| Structure | Footprint | Area | A dining set for six | A two-seat lounge group | A grill with working space |
|---|---|---|---|---|---|
| Louvered Pergola 10×12 | 10×12 ft | 120 sq ft | Exact fit — no spare on one side | Fits — 3 ft to spare | Fits — 5 ft to spare |
| Louvered Pergola 12×16 | 12×16 ft | 192 sq ft | Fits — 3 ft to spare | Fits — 5 ft to spare | Fits — 8 ft to spare |
Every verdict above is calculated from the footprint the manufacturer publishes and the clear floor a furniture group needs, compared longest side to longest side. Ground conditions, walkways and local rules are not in the arithmetic. Measure the patio before ordering.
What the extra 72 square feet buys
Not a bigger table. The same dining set for six goes under both. What the larger structure buys is the space around it: room to push a chair back and stand without leaving the roof, room for a serving table against a post, room for a lounge chair in a corner. A 10×12 covers furniture; a 12×16 contains a room.
Curtains against screens
The 10×12 comes with waterproof curtains and bug mesh. The 12×16 uses six pull-down screens. Curtains drape and move in a breeze, which is fine for privacy and shade and imperfect against insects. Screens close the side properly, which is what makes an evening usable when a draped structure is not.
Which constraint decides
If the patio is the constraint, measure before choosing. A 12×16 needs clearance outside its posts, so the slab has to be meaningfully larger than 12 by 16.
If the use is dining only, the 10×12 does the job at a smaller footprint.
If evenings and insects matter, the screens on the 12×16 are the feature to pay for, not the area.

Questions
Is a 12 by 16 pergola too big for a normal patio?
It needs clearance outside the posts as well as its own footprint, so the patio has to be meaningfully larger than 12 by 16 feet.
Do both fit a table for six?
Yes. The 10×12 fits it exactly; the 12×16 leaves room to walk behind a pushed-back chair.
What is the difference between curtains and screens?
Curtains drape and move in wind. Screens pull down and close the side.
