Jamb vs. Reveal: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 14, 2023
A jamb is the vertical side of a door or window frame. Reveal is the side of an opening for a window or door between the frame and the outer surface or the act of making something known.

Key Differences

A jamb refers to the vertical side parts of a door or window frame, providing structural support. On the contrary, reveal has a dual meaning; architecturally, it denotes the side of an opening for a window or door between the frame and the outer surface. Moreover, in general context, to reveal means to disclose or make something known.
While jamb is a specific term mostly used in architecture and construction, reveal has a broader usage in the English language. The reveal can be both a noun, referring to a part of a structure, and a verb, indicating the action of showing or disclosing something.
Jambs play an essential role in the construction and installation of doors and windows, ensuring they sit correctly within a structure. On the other hand, reveal as an architectural term might describe how much of a window or door is visible, while as a verb, it's about disclosure and presentation.
When discussing door or window installation, one might refer to both jamb and reveal. The jamb being the structural component, and the reveal discussing the aesthetic and functional aspects of how the window or door appears within its setting. In everyday conversation, however, reveal is more likely to be understood as disclosing something hidden.
