How to Measure for Your New Attic Ladder
Determine whether the chosen location allows sufficient “projection” and “landing space” for your unit. Watch out for electrical wiring.
- Place your ladder securely below the ceiling hatch and lock it in place. Leave room for extending the measuring tape on one side of the hatch. Climb up and open the ceiling hatch.
- Extend the tape measure so that it reaches from the ceiling to the floor. Have your helper below note the measurement at the floor level. This gives you the measurement for folding attic stairs.
- Hold the tape measure through the “rough opening,” or open hatch, of the attic at the floor level. The distance from the attic floor to the floor below gives you the measurement for a “disappearing” or non-folding stair.
- Measure the inside width of your attic’s rough opening as well, and make note of that measurement. You will need to know how wide the stairs can be before you order them, whether they are folding or non-folding.
