The distance view and character budget are practical comparisons, not a visibility guarantee. Venue lighting, glare, movement and sightlines affect the real result.

What the result means

Shorter allows larger letters

Removing words gives every remaining letter more screen area, making the message more noticeable at the same distance.

Contrast is calculated

The simulator uses the WCAG relative-luminance formula. Its references describe text contrast—not concert visibility.

Test it from your seat

Use full brightness where allowed, keep the phone below other fans’ view and follow the venue’s rules.

Contrast method: W3C Understanding WCAG 2.2, Contrast (Minimum).
