Bordure Border Width Fraction Calculator
Observed bordure width fraction of caller horizontal field envelope.
Description
A bordure width can be normalized by field width to compare scales.
A bordure width can be normalized by field width to compare scales.1
This simple fraction does not enforce every geometric or heraldic constraint on a complete border.
When to use Bordure Border Width Fraction Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the source tradition, viewing frame, coordinate units and independently annotated features.
How to use Bordure Border Width Fraction Calculator and understand its results
- Establish the source tradition, viewing frame, coordinate units and independently annotated features.
- Enter bordureWidth, fieldWidth, using the field meanings and rules below, then run the tool.
- Read result.observedFraction, using the output meanings and calculation rules below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| bordureWidth | Bordure width | number | Required |
| fieldWidth | Field width | number | Required |
Use a positive field width and nonnegative bordure width no greater than it. Return bordureWidth/fieldWidth; values above one-half are accepted in this simple ratio model.
widthFraction=bordureWidth/fieldWidth Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.observedFraction | observed Fraction; dimensionless fraction, not a percent | number |

}Limitations and assumptions
The ratio does not enforce complete-border fit, field height, curved outlines or a universal preferred width.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Orle Inner Margin Width Calculator: An orle inset and a bordure width describe different positions relative to the field edge. For a complementary comparison, use Ordinary Width Proportion Checker (chief/fess/pale/bend): Ordinary-width review depends on the selected drawing and proportion standard.
