Why we like it

Aspect Ratio Setter earns its place in the superhive library for a focused job: managing render output sizes on a per-camera basis instead of editing render settings by hand each time.

What is Aspect Ratio Setter?

Aspect Ratio Setter is a Blender add-on from AL3K that assigns custom render resolutions to individual cameras. Rather than manually updating render settings each time you change output size, you set an aspect ratio per camera, and the render resolution updates automatically when you switch the active camera.

The add-on ships with built-in presets covering standard, vertical, cinematic, and social media formats, including YouTube, Instagram, and TikTok. You can also enter your own aspect ratios manually and save them as custom presets to reuse your most-used settings. This suits work spanning animations, reels, YouTube videos, and story content, where different cameras may need different output formats within one project.

It's built for Blender 4.4 and later and distributed under the GPL license. The interface is lightweight with no complicated setup, and the Aspect Ratio panel lives in the Render Properties tab, or the Camera Data tab after you select a camera.

Who is Aspect Ratio Setter best for?

Aspect Ratio Setter is best for artists, filmmakers, and content creators producing animations, reels, YouTube videos, or story content who need different output formats across cameras in one project.

Frequently asked questions

What Blender version does Aspect Ratio Setter require?

Aspect Ratio Setter is built for Blender 4.4 and later, so you'll need that release or newer to run it. The add-on adds an Aspect Ratio panel for assigning render resolutions per camera, switching between formats, and saving presets. If you're on an earlier Blender version, check the developer's page before installing to confirm whether an older build is available, since the stated requirement here is Blender 4.4+.

How do I install Aspect Ratio Setter in Blender?

Aspect Ratio Setter installs like a standard Blender add-on. Download the Aspect Ratio Setter zip file, open Blender, and go to Edit > Preferences > Add-ons. Click Install, select the zip file, and confirm with Install Add-on. Then enable it by checking the Aspect Ratio Setter entry in the list. Once active, open the Render Properties tab, or select a camera and open the Camera Data tab, to find the Aspect Ratio panel.

Can I create and save my own aspect ratios in Aspect Ratio Setter?

Aspect Ratio Setter lets you enter your own aspect ratios manually alongside the built-in presets for YouTube, Instagram, TikTok, and other formats. You can save those custom formats as presets and reuse your most-used settings without re-entering them. Everything works per camera, so different cameras in the same project can output different sizes, and the render resolution updates automatically whenever you switch the active camera.

Is Aspect Ratio Setter free to download?

Aspect Ratio Setter is listed as free in this catalog. Licensing and pricing can change over time, so check the developer's page for current terms before you download. The add-on is distributed under the GPL license. Once installed, you get per-camera aspect ratios, built-in social media presets, custom format support, and automatic render resolution updates when switching cameras, all within a lightweight, intuitive interface.
