All-Caps Size Compensation Percent
Caller explicit SIGNED all-caps additive percent compensation, size positive; not universal optical equivalence. Explicit caller font/layout/reference context; not a shaping engine, actual page layout or accessibility certification.
Description
All-capital text can be scaled under an explicit optical compensation policy.
All-capital text can be scaled under an explicit optical compensation policy.1
The signed percentage expresses an additive change to the base point size.
When to use All-Caps Size Compensation Percent
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish the font version, feature, layout, physical or CSS units, and matched reference basis needed for this calculation.
How to use All-Caps Size Compensation Percent and understand its results
- Establish the font version, feature, layout, physical or CSS units, and matched reference basis needed for this calculation.
- Enter observedBodyFontPoints, callerAllCapsCompensationPercent, following the field table and rules below, then run the tool.
- Read callerAdjustedAllCapsPoints. 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 |
|---|---|---|---|
| observedBodyFontPoints | Observed body font points | number | Required |
| callerAllCapsCompensationPercent | Caller all caps compensation percent | number | Required |
Enter a positive base size and a finite compensation percentage strictly greater than −100. Multiply by one plus percentage divided by 100, keeping the resulting size positive. Optical equivalence is not evaluated.
adjustedPoints=basePoints×(1+compensationPercent/100) Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerAdjustedAllCapsPoints | Caller adjusted all caps points | number |

}Limitations and assumptions
The calculation uses declared units and font or layout assumptions. It does not shape glyphs, lay out actual pages, or certify accessibility or print quality.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected.
Alternative or Complementary methods
For a related review, use Small Caps Size Percent Lookup: Small-cap height depends on the font and feature being measured. This lookup compares your observed relative height with a verified reference under an exact font-and-feature key. For a complementary step, use Baseline Shift Superscript Percent: Superscript baseline movement is separate from superscript glyph size. This calculator applies a supplied signed baseline-rise percentage to the base font size.
