Zeeldom on Instagram: "Measuring a perfect corner is all about accuracy, alignment, and using the right tools.

For larger areas, like walls or floors, use the 3-4-5 method, a basic geometry trick: measure 3 units on one side of the corner, 4 units on the other, and check if the diagonal between them is exactly 5 units.
