Measure what must be measured.
Compare what can be compared.
Old workshop saying
01
Most of the time I am not really interested in measuring.

This may sound odd coming from somebody who spends much of his time checking dimensions, setting out floors, and worrying about millimetres. Yet many problems are better solved through comparison than measurement.

02
A straight edge does not tell me how high a floor is. It tells me whether the floor is flat. A square does not tell me the angle. It tells me whether the angle is square. A template does not describe a shape. It tells me whether the shape is correct.

I am not measuring. I am checking.

03
A tape measure tells me a number. A straight edge tells me if something is right. Those are different questions.

When preparing a floor for tiling, I am rarely interested in the exact height of a particular point. What matters is whether the floor is flat, too high, or too low. I do not need a number. I need an answer.

The same applies to setting out. I can measure every cut around a room, but what I really care about is whether the cuts relate properly to one another. Whether they appear balanced. Whether the pattern sits comfortably within the space.

04
Most work is like that. Measurement produces numbers. I am interested in relationships.
