Pinch Area Calculator
Calculate precise measurements for tight spaces, narrow areas, and confined dimensions.
Perfect for construction projects requiring accurate calculations in restricted spaces.
Constrained Clearance & Fit Optimization Guide
Core Clearance Math
- Available Height = OpeningH − 2 × SafetyMargin
- Available Width = OpeningW − 2 × SafetyMargin
- Rotated Footprint (angle θ): H' = Hcosθ + Wsinθ • W' = Wcosθ + Hsinθ
Decision Flow
- Check straight fit → if fail evaluate rotation angles (15° increments)
- Still fail → remove trim / hardware or partial disassembly path
- Persist fail → alternate access (window / larger door)
Risk Indicators
- Clearance < 0.25" each side for rigid object → high scuff / jam probability
- Angle approach increases effective diagonal beyond opening
- Ignoring protrusions (hinges, handles) in width model
Optimization Tactics
- Remove doors from hinges (adds 0.75–1.0" typical width)
- Detach handles / feet (appliances) lower height pass line
- Use furniture sliders to reduce required tilt angle friction
Measurement Protocol
- Record opening at top / mid / bottom: use minimum
- Map obstruction protrusions separately (electrical boxes, trim returns)
- Photograph sequence for later dispute / planning reuse
FAQ
- Why angled calculation? Tilting reorders projection lengths enabling marginal fits.
- Safety margin size? 0.5–1" typical residential; high‑risk finish surfaces stay ≥1".
- Soft goods? Use compressibility factor to reduce modeled dimension.
Action Tip: For borderline cases, simulate with cardboard template cut to largest face before committing move.
