HeyGen publishes a pixel range, not a ladder

The usage limits page states that width and height must each be between 128 and 4,096 pixels. No named tiers appear, so the cell holds a permitted region rather than a list of choices, and everything inside it is reachable. As of 2026-09-22.

Inclusion rule. Output size statements on this usage limits page. Upload ceilings for input files are a different column and are recorded on the file axis. Order. Width, then height, then the constraint that narrows both.

1Bounds and ladders are not the same kind of fact

A ladder says which sizes exist. Bounds say which sizes are refused. Everything between 128 and 4,096 is permitted here, so a placement asking for an exact pixel size can be served exactly rather than at the nearest rung above it.

That has a real consequence for delivery. Several rejections at upload come from odd pixel counts after a crop, and a row that accepts arbitrary dimensions can be asked for the even numbers a platform expects rather than cropped into them afterwards.

2The shape list narrows what the bounds appear to offer

Two dimensions free between 128 and 4,096 sounds like any shape at all. The same page publishes two aspect ratios, sixteen by nine and nine by sixteen, and that list is the binding statement. The bounds govern size within those shapes rather than shape itself.

Reading one column without the other is how this row gets misread. A square placement is not served by a page that permits 1024 by 1024 pixels and lists no square ratio, and the register keeps both cells filled so the contradiction is visible.

34,096 is the highest number in this column

The upper bound exceeds every named tier in the register, including the two 4k figures, which sit near 3,840 on their long side. Nothing in the advertising formats read here needs it, so the figure is another instance of a ceiling that is accurate and inert.

Its comparative value is in what it says about the product. A page that bounds output between a thumbnail and something larger than 4k is describing a general-purpose renderer, not an advertising tool, and every other figure on the row reads the same way.

4Where this cell sits in the column

Inclusion rule. Every generator in the register, carrying the resolution figure its own page prints, whether that is a ladder, a range or a single pair of numbers. Order. Alphabetical by generator name.
