Practical tools for measured work
Measured belt size and hole positions
Convert a measured wearing length into belt size and leather-fold hole positions with explicit buckle allowance.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
Hole centres from leather fold
| Hole | Distance (mm) |
|---|---|
| 1 | 750 |
| 2 | 775 |
| 3 | 800 |
| 4 | 825 |
| 5 | 850 |
How it works
Measure a well-fitting belt from the buckle tongue base to the hole you use, or measure around the position where you wear the belt. The Hermès reference example is an 85 cm wearing measurement and an 85 size label. Other brands may label differently.
For leatherwork, subtract the measured buckle contribution to locate the centre hole from the leather fold. Add equally spaced holes around it and the entered tip allowance. Transfer the fold-to-centre dimension to the belt-hole template for a full-size layout.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Measurement units
- cm
- Buckle tongue base to used hole
- 85 cm
- Buckle contribution before leather fold
- 5 cm
- Odd number of holes
- 5
- Hole spacing
- 2.5 cm
- Last hole to strap tip
- 6.5 cm
Primary result: Measured belt size: 85 cm.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
Do not substitute trouser labels or total strap length for the wearing measurement. Buckle geometry, fold allowance, leather stretch and brand size increments vary. The fold-to-tip result excludes the folded-back attachment; add that allowance from your actual hardware pattern.
Frequently asked questions
What should I verify before using this result?
Check the input values, units, dates and assumptions. Compare the method and its stated limits with the source relevant to your task.
Why might the finished result differ?
Results depend on the entered data and the model’s assumptions. Rounding, changing conditions or omitted factors can affect the comparison. Read the limitations before using the result.
