72x80 Sliding Glass Door Size & Fit — Rough Opening vs Frame Size (Avoid Costly Rework)
What “72x80” means in real installs (buyers get this wrong)
Most shoppers say “72x80” and assume it equals frame size. It usually doesn’t.
We treat 72 in × 80 in as the rough opening. The frame runs about 0.6" smaller in both width and height. Installation needs clearance. Crews need room for shims and leveling.
Rough opening: the hole in the wall.
Frame size: the door unit you slide into it.
0.6" allowance: helps avoid bind, scrape, uneven reveal.
| Item | What you measure | Why it matters |
|---|---|---|
| Rough opening | Framing-to-framing W × H | Quote starts here |
| Frame size | Unit size shipped | Fits after tolerance |
