Sightline & Screen Height
Set room depth, rows, rake, and screen bottom height. See which rows can see the bottom of the screen over the heads in front, plus 2× / 6× image-height viewing guidance.
Use at your own risk. Geometry is simplified (flat floor or constant rake, uniform head height). AVIXA 2× / 6× image-height distances are rule-of-thumb guidance for basic viewing — confirm for content type and local standards. Always verify on site.

Sources
- Seated eye height default ≈ 3.75 ft (3′9″) — common planning figure; edit for your audience.
- AVIXA-style guidance often cited for basic viewing: farthest viewer within ~6× image height; nearest ~2× for detailed/analytical content categories differ — labelled here as guidance only.
- Sightline clear if the line from eye to screen bottom passes above the head of the row in front.
What this sightline checker does
It draws a side view of seating and screen, flags rows that cannot see the bottom of the image over the heads in front, and shows 2× / 6× image-height distance guidance.
Tips
- Raise screen bottom or add rake to clear rear rows.
- Stagger seats when possible.
