Star Grid Row Spacing Calculator
Equal-cell star-row centers inside explicit canton height with half-cell edge margins, not an official national star layout.
Description
Equal-cell star rows place centers halfway inside each cell, leaving half a cell at the upper and lower edges.
Equal-cell star rows place centers halfway inside each cell, leaving half a cell at the upper and lower edges.1
The row count and available canton height determine the spacing.
When to use Star Grid Row Spacing Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
How to use Star Grid Row Spacing Calculator and understand its results
- Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
- Enter availableCantonHeight, starRows, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| availableCantonHeight | Available canton height | number | Required |
| starRows | Star rows | number | Required |
Enter a positive available height and an integer row count from one to sixty-four. Return one center coordinate per row and the common spacing, in the input length unit.
spacing=H/n; centerY_i=(i+0.5)H/n Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.equalCellCenterY | Equal Cell Center Y | list |
| result.rowSpacing | Row Spacing | number |

}Limitations and assumptions
The calculation uses supplied geometry, observations, or annotations. It does not establish an official construction specification, national identity, or universal design quality.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related review, use Staggered Star Row Offset Calculator: Alternating star rows may have a measured horizontal stagger. Comparing their first centers with the column spacing expresses that offset both as a length and as a spacing fraction. For a complementary step, use Circle of Stars Ring Radius Calculator: A circle of star centers must leave room for each star’s radial extent and an edge margin. The available diameter therefore bounds the radius of the center ring.
