WHY IT’S USEFUL
A layout that looks close can still be out of square. Build Specs turns two measured legs into the diagonal you need to check a deck, foundation, wall, or other rectangular layout before the error carries into the rest of the work.
WHAT IT DOES
Useful detail without the spreadsheet.
01
Find the diagonal
Enter two known legs to calculate the corner-to-corner diagonal using the Pythagorean theorem.
02
Find a missing leg
Start with a known diagonal and one side when the layout needs a missing dimension filled in.
03
Buildable dimensions
Work in decimals or fractions, then read the result back in total inches or feet and inches.
USE IT WHEN
The answer needs to travel with the work.
✓Squaring a deck, foundation, wall, or rectangular pad
✓Checking a corner-to-corner measurement before fastening the layout
✓Finding one missing side when two dimensions are already known
