FormulaProjected vertical slat coverage = width*Math.sin(angle*Math.PI/180); Front-view open gap = Math.max(0,pitch-width*Math.sin(angle*Math.PI/180)); Front-view open fraction = Math.max(0,pitch-width*Math.sin(angle*Math.PI/180))/pitch

How to use this tool

  1. Enter slat width, vertical slat center spacing, and slat tilt from horizontal in the displayed units.
  2. Calculate and use each labeled result for blind slat projected gap. Compare the result with a measured sample before committing materials.

Try this example

{
  "width": 25,
  "pitch": 22,
  "angle": 45
}
