Blind Slat Count Calculator
Estimate slats from window height and pitch.
How the Blind Slat Count Calculator works
Blind Slat Count Calculator turns window height inches and slat pitch inches into slats. It computes that as window height divided by slat pitch.
Worked example: with Window height inches 60, Slat pitch inches 2, this tool returns slats 30 slats, window height 60 in, slat pitch 2 in. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
