area

Hello,

I drew walls for a 10' x 10' room, and it should show a living area of 100 sq ft, but it displays 105 sq ft and 87 sq ft in others. I understand interior dimension is 9'4 x9'4. Please advise on how to resolve this issue.

Deja Vu ?

You are measuring to the ext. surface layer vs. The studs.

Studs are 10'x10' =100'

Surfaces: 10.25'x10.25 = 105'

 

Change default to measure to main layer.

 

Also, 9.33'x9.33' =87'

Thank you for your reply. When people talk about their house's square footage, should I use the area measured to the studs or the surface area of the walls?

Very respectfully,

depends on who is asking. The jurisdiction here is to the outside of the outside wall (studs but could be sheathing, no one really asks). Realtors have a different definition. Surveyors here measure to the foundation.

Stairs' square footage interesting thought regarding ANSI Z765-2021 Square Footage - Method for Calculating:

 

The area of stairs is included in living area for every floor they access. Many builders and physical-minded people usually want to count the stairs in a 2-story build once (not twice), even if you have storage under part of the stairs. But if you consider a 10-story building with nine flights of stairs, then you see that counting the stairs on every floor might be best.
