The Dimensions Of Internal Doors?

Standard interior door sizes are a common feature in both new and old construction-style homes. They are generally 32″ wide and 80 inches high, with a typical thickness of 1 ⅜”. The standard width can range from 24″ to 36″ depending on the size of the doorway and the materials used. When building an accessible space, it is essential to find the ideal interior door size based on room dimensions and location.

Pre-hung doors and frames typically measure 32″ or 36″ in width. Slab doors typically have a thickness of 1-3/8″ to 1-3/4″. The standard door height for interior passage doors is 80 inches, while closet doors may be slightly shorter at 78 inches. As placed inside a house, an interior door is slightly smaller than an exterior door at 80″ x 32″ (203cm x 81cm).

Customary interior doors require 2″ (51 mm) for width and 2 ½” (64 mm) for height. However, each door manufacturer has their own R.O. requirements for every model they make, such as fire-rated doors. Most interior and exterior door panels are 80 inches tall (or 6′ 8″), as required by many building codes. Other common heights are 84 inches (7′) and 96 inches (8′).

The minimum recommended door width to allow persons with disabilities to pass through is 36 inches. The most common interior door widths are 2-0, 2-4, 2-6, 2-8, and 3-0, which translate to 24, 28, 30, 32, and 36 inches wide. To determine the nominal door size, measure the width and height of the existing door slab and round each number up to the nearest inch.

In summary, standard interior door sizes are crucial for creating an accessible space in both new and old construction-style homes.

How do I measure what size interior door I need?

The process for determining the door width and height involves a thorough understanding of the stud wall structure.

Do interior doors come with hinge cutouts?

Door slabs typically do not come with hinge cutouts, but some sellers offer the option to mortise the hinge placement. They are sold with door handle cutouts.
