Equal Slat & Divider Spacing Calculator
Lay out equal-width slats or dividers with equal gaps, including the gaps at both ends.
Set up your calculation
An illustrative example is loaded. Replace its values with your measurements, costs or documented settings.
Calculation
Your result
- Equal gap
- 75 mm
- First slat center
- 90 mm
- Center-to-center pitch
- 105 mm
- Last slat center
- 510 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
Clear gap = (opening width − count × slat width) ÷ (count + 1). First center = gap + half slat width. Center pitch = slat width + gap.
- All gaps, including the two end gaps, are equal. Dimensions are measured along a straight opening.
- This is layout geometry, not guidance for guards, railings or child-safe openings. Check applicable requirements separately.
Work through the equal spacing example
| Input or step | Example value |
|---|---|
| Example inputs | 600 mm opening; five 30 mm slats |
| Equal gap | 75 mm |
| First slat center | 90 mm |
| Center-to-center pitch | 105 mm |
| Last slat center | 510 mm |
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.
