Table Leg & Board Taper Calculator
Calculate a straight taper angle and layout offset from end widths and taper length.
Set up your calculation
An illustrative example is loaded. Replace its values with your measurements, costs or documented settings.
Calculation
Your result
- Offset per tapered edge
- 30 mm
- Angle per tapered edge
- 2.862 °
- Tapered edge length
- 600.75 mm
The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.
Method & assumptions
One-sided offset = wide end − narrow end. For a symmetric taper, each edge takes half that difference. Edge angle = atan(offset ÷ taper length).
- The length is measured along the original straight reference axis. Symmetric mode divides the change between two opposite edges.
- This supplies layout geometry, not a jig or saw setup. Leave stable reference surfaces and use the machine manufacturer's workholding guidance.
Work through the taper angle example
| Input or step | Example value |
|---|---|
| Example inputs | 600 mm taper from 60 mm to 30 mm; one-sided |
| Offset per tapered edge | 30 mm |
| Angle per tapered edge | 2.862405 ° |
These values match Load example. They illustrate the method, not recommended material, machine or pricing settings. Read the assumptions before using the result.
Common questions
Are the example settings a recommendation?
No. Replace the example with measured dimensions, actual costs and your product or machine manufacturer's limits.
What if an input is incomplete or impossible?
The result is hidden and a field or calculation error explains what needs correction.
Use this in your project
Continue with the next measurement or cost, then keep the assumptions with your quote.
