Pocket Door Sizes Guide
A Door Expert’s Guide to Measuring Your Pocket Door
Posted on May 23, 2025, by Bruno Rocca
As a door expert, I’ve spent years helping homeowners and builders select and install the perfect doors for their spaces. One of my favorite types to recommend is the pocket door—a stylish, functional solution for maximizing space in any room.
What is a Pocket Door?
Imagine a door that doesn’t swing open but instead slides smoothly along a track and disappears into a hidden compartment, or “pocket,” inside the wall. That’s a pocket door—perfect for tight spaces, closets, bathrooms, and anywhere a swinging door would get in the way.
Understanding Door Measurements: Nominal vs. Actual Sizes
- Nominal Size: The rounded size used for labeling (e.g., 24 x 80 inches).
- Actual Size: The precise measurement of the door slab, slightly smaller than the nominal size.
- Rough Opening: The size of the wall hole for the door and frame—always larger than the door slab.
Below are standard measurements for Belldinni pocket doors, with tables for easy reference (in inches and feet).
Pocket Door Height Measurements
| Nominal Door Height (in) | Nominal Slab Height (ft) | Actual Door Height (in) | Actual Slab Height (ft) | Rough Opening Height (in) | Rough Opening Height (ft) |

- Nominal Door Height: The labeled height (e.g., 80 in).
- Actual Door Height: The precise slab height.
- Rough Opening Height: Height of wall opening (includes frame & track).

How to Measure for a Pocket Door
- Check the wall: It must be non-load-bearing and free of major obstructions (wiring/plumbing).
- Gather tools: Tape measure, paper & pencil, camera (optional).
- Measure wall space: For the pocket and the doorway.
- Calculate rough opening: Typically, width = 2 x door width + 1 in; height = door height + 4.5 in.
