If one cuts the beginning squares on bias the ending squares will have straight grain edges. I do like to have the final half square triangles a bit larger so they can be trimmed to exact size.
A walking foot helps in sewing bias edges.

These measurements were listed previously but I find they seem to be small. My samples have needed the beginning block 1/4 to 1/2 larger. Best to make a sample and if half square triangle block is too big trim it down.
Starting Block
2" 1"
2 1/2" 1 1/2"
3 1/2" 2"
4" 2 1/2"
5" 3 1/2"
6" 4" I use 6 1/4 for 4" block
7" 4 1/2"
8" 5"
8 1/2" 5 1/2"
9" 6"
10" 7"
Starting Block
2" 1"
2 1/2" 1 1/2"
3 1/2" 2"
4" 2 1/2"
5" 3 1/2"
6" 4" I use 6 1/4 for 4" block
7" 4 1/2"
8" 5"
8 1/2" 5 1/2"
9" 6"
10" 7"

Agree with the need to make the start blocks a bit bigger and then trim down. The accurate maths would be great. The Easy Angle ruler makes very accurate half-square triangles, although not as fast as the method here.
