Description
Subtract half the sum of firstWidth and secondWidth from pitch for edgeGap.
A signed fit margin compares available space with an object and explicit allowances. Volume sufficiency, radial gaps, and diametral clearance are different conditions.
Subtract half the sum of firstWidth and secondWidth from pitch for edgeGap.
When to use this tool
Use Button Pitch Edge Clearance Budget when you need one transparent product fit or travel-margin term.
How to use the tool and how it works
- Enter pitch, firstWidth, secondWidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read edgeGap. Use the output convention below.

}Limitations and assumptions
- Pitch is center-to-center and widths must be aligned on that axis; no finger-clearance, accessibility, tolerance, or actuation criterion is applied.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check complete three-dimensional geometry, tolerances, materials, and operating conditions before judging actual fit or safety.
