Question

Why did Gerrit Rietveld use lumber cut in standard size for his Red-Blue chair?

Answer:

if you are a plato/edmentum user this is the answer

Answer 2

He had hoped his chair(s) would go on to be mass-produced, not hand-crafted. As a matter of fact, he had hopes that much of his furniture would be mass-produced--he aimed for simplicity in construction. The pieces of wood that comprised the Red Blue Chair were the standard lumber sizes readily available at the time.
