Author: Reinhold Harris  |  Last update: Wednesday, March 5, 2025

To get a perfectly square corner, you want to aim for a measurement ratio of 3:4:5. In other words, you want a three-foot length on your straight line, a four-foot length on your perpendicular line, and a five-foot length across. If all three measurements are correct, you'll have a perfectly square corner.

What is the golden rule of tiling?

The golden rule is, try as much as possible to avoid small pieces of tile, or, try to keep them hidden. The same basic idea applies to the vertical lines of your job. Try to minimise any small cuts. It is best to start with a centre line and mark along your wall where each vertical joint will occur.

What is the 3 4 5 method for tile?

Starting at one point on the baseline, measure and mark 3 feet (or another unit) along it. From that same starting point, measure 4 feet perpendicular to the baseline and mark this point as well. Measure between the two points you just marked. If the distance is 5 feet, your lines form a perfect 90-degree angle.

What is the best ratio for tile?

How to mix tile mortar starts with balancing the proportions between cement, sand, and water. For most standard tile mortar mixes, a 4:1 (four parts sand to one part cement) ratio is optimal. This mix ratio provides a strong foundation without sacrificing flexibility.

Basically, the golden ratio is 1.618 to 1. For tile purposes, this doesn't have to be exact so we can round it to 60/40. If A=60 and B=40 then C=100. The ratio of A to B is the same as C to A.
