How to Measure an Attic Ladder Rough Opening · Step 4 of 4
In this video
The first step is to determine the correct opening size for the attic ladder. Measure the width of the existing opening, specifically between the trusses. In this video, the opening measured 22.5 inches. This width is crucial as most trusses are set 24 inches on center, providing a standard 22.5 inches between them. Next, measure the length of the opening, which was 63 inches in this case. Finally, measure the distance from the ceiling to the floor (ceiling height). This measurement will dictate the required length of the attic ladder, as ladders come in various lengths to accommodate different ceiling heights (e.g., 54" L x 22.5" W for 8-9' ceilings, 63" L x 22.5" W for 10-12' ceilings). This particular installation is for a ceiling over 10 feet high, requiring a longer ladder that can extend up to 12 feet.
