Description
Uniform grommet positions can be calculated from an already selected count and edge offset.
Uniform grommet positions can be calculated from an already selected count and edge offset.1
Spacing geometry leaves fastener strength and the required attachment design to separate assessment.
When to use Grommet Spacing Recommendation Calculator
Use this tool to apply the stated grommet spacing recommendation calculator operation with an explicit input and unit basis.
How to use Grommet Spacing Recommendation Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualHoistLength, callerActualEdgeOffset, callerIndependentRequiredGrommetCount and run the tool.
- Read result.grommetCenterPositions, result.uniformCenterSpacing using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualHoistLength | Hoist length, on the basis specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
| callerActualEdgeOffset | Edge offset, on the basis specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
| callerIndependentRequiredGrommetCount | Required grommet count, on the basis specified in the algorithm. | number | required; finite; integer from 2 to 64; further conditions in the algorithm |
Require positive hoist, nonnegative offset, integer count 2–64 and positive hoist minus twice offset. Place centers evenly across that usable span.
centerᵢ = offset + i × (H − 2offset)/(count − 1) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.grommetCenterPositions | Positions from the chosen reference edge, in ascending order. | array |
| result.uniformCenterSpacing | Gap between adjacent centers in the supplied length unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Number-of-Stripes Parity Checker. Alternating two-color stripes have matching end colors when their count is odd and different end colors when it is even.
For a related operation, use Sewn Stripe Panel Cut List Generator. Sewn horizontal stripes may have unequal finished heights.
