Reserve the busy regions first
On 1920×1080, reserve the camera, chat panel, alerts, and captions, then place lyrics in the lower third or beside the performer.
On 1080×1920, comments and gifts fill the lower screen, so lyrics move to an upper-middle band above the comment stream.
Placement, not sizing
This tool decides where the lyric block goes. The Browser Source size calculator decides how big the source is; use both together.
Do not stretch one Overlay between 16:9 and 9:16. Build a separate source per orientation so anchors stay honest.
Use the tool
1920×1080: reserve camera, chat, alerts, captions; lyrics in the lower third. 1080×1920: reserve comments and gifts; lyrics in an upper-middle band.
Frequently asked questions
Does this replace the size calculator?
No. This plans placement; the size calculator sizes the Browser Source. They complement each other.
Where do lyrics go on a vertical scene?
Above the comment stream, away from face, gifts, and platform controls.
Can I reuse one overlay for both ratios?
No. Build one source per orientation so anchors and font ranges stay correct.
