Timber door frames come in various sizes, designed to accommodate standard door dimensions. The size of the timber door frame typically refers to the overall external dimensions of the assembled frame. These external dimensions are larger than the actual door size to allow for the frame material and necessary clearances.
According to the information from Doordeals, here are examples of standard timber door frame sizes, specifically the overall external dimensions for ready-made hardwood single door frames, based on common door sizes:
| Door Size | Overall External Door & Frame Dimensions |
|---|---|
| 30" x 78" (762mm x 1981mm) | 33.5" x 81.5" (851mm x 2070mm) |
| 32" x 80" (813mm x 2032mm) | 35.5" x 83.5" (902mm x 2121mm) |
| 33" x 78" (838mm x 1981mm) | 36.5" x 81.5" (927mm x 2070mm) |
| 34" x 82" (864mm x 2082mm) | 37.5" x 85.5" (952.5mm x 2172mm) |
These dimensions represent the size of the opening required in the wall to install both the frame and the door together. The actual timber profiles used to construct the frame have specific widths and thicknesses, which contribute to these overall external dimensions. The size you choose depends directly on the size of the door you plan to install.
