In the drawing to the right, the layouts are sectioned off into easily measurable rectangles. This is an example for how these common counter-top shapes should be measured:

You just take the Length x Width of each section, and add it together.
For our U-shaped Counter-top example, we would measure it like this:

Piece A: 62.5” x 25” = 1562.5”
Piece B: Same size as A in this case, so 1562.5”
Piece C: 125” x 25” = 3125”
=6250 square inches

Now, we don’t buy these materials by the square inch so we will need to convert that number into square feet.

A square foot is 12” x 12” = 144. So let’s divide 6250 by 144 to get our final square footage of 43.403.

We always round up when measuring so the final measurement would be 44 square feet.
