How do I measure square footage of a bathroom for flooring?

Answer 1

Measure from inside of wall to inside of wall. Do this length ways and side ways. Then multiply the numbers of feet that you get to each other.
If it is say 10ft wide and 15ft long multiply 10ft time 15ft. answer would be 150sq ft for this one.
If floor is odd shaped then get as close as you can and just add a little more to it.

Answer 2

Answer number one is valid, though I too have thoughts. Sq. Ft. is length multiplied by width.

In your case; as well as others it may be that there are bits and pieces that intrude throughout the bathroom,,,or any room, creating an issue of taking more measurements than might be neccesary.

The more important issue in any case; is to measure the widest spans, both in length and width, and BUY to that measurement, even accounting for cut and waste.

Example: The room size is 10 x 10. In that measurement, certainly you need not consider UNDER the tub or shower, or even UNDER a vanity, but you should consider Pulling a toilet, or going into a linen closet, possibly in the corner of the bathrooms total space.

For any angles... Floor not directly in a dimension that doesn't include a shape not exactly square or rectangular,,,or even one curved/rounded,,,you'll need to interpret the most distant measurements and adjust as you install. It might be that in a 10x10 you only need to have 10 x 9.5 showing, but should consider all the transitional areas. That would equate first of all; to HOW any material you choose is sold, and then YOU working the material into the pattern that exists. The point is, when you're in your bathroom and look at the walls, it may be 10x10, but a view from the ceiling might make the floor and possible cuts, look like a piece from a jig saw puzzle.

Better to allow for waste, than to patch and paste.

Answer 3

measure lengh then width and multiply the two
eg 5 feet lengh 4 feet width
5 x 4 = 20 sq feet
