Problem
A creator uses all-caps captions designed for a high-contrast horizontal layout, but the longer words create excessive line wrapping in narrow vertical frames.
Solution
Root Cause / Diagnostic:
All-caps typography occupies up to 30% more horizontal linear space than mixed-case (Title Case or sentence case) lettering due to uniform cap heights and wider glyph metrics. In a restricted 9:16 vertical viewport, multi-syllabic capitalized words cause unexpected line breaks, resulting in awkward fragments and visual clutter.
Actionable Fix:
1. Switch mobile vertical caption formatting from all-caps to sentence case or title case to reduce overall text footprint.
2. Select condensed or narrow font variants (such as Bebas Neue or Anton) with tight letter-spacing (-1% to -2% tracking) when uppercase styling is required.
3. Limit caption chunks to a maximum of 3 to 5 words per subtitle card to prevent text from wrapping past safe horizontal margins.
Pro Tip:
Reserve uppercase text exclusively for single-word visual accent pop-ups rather than applying it to continuous multi-line spoken subtitles.
