Camera Aspect Ratio Guides earns its place for combining camera-viewport composition overlays with render burn-in in a single panel, handled through non-destructive compositor nodes that leave your existing node tree intact.
Camera Aspect Ratio Guides provides real-time composition overlays in the Blender camera viewport, with the option to burn guides into final renders. Composition guides cover the Rule of Thirds, Golden Ratio (1:1.618), Golden Triangle, Diagonals, Center Cross, and Harmonious Triangles.
Aspect ratio presets can be shown simultaneously in one view, each with custom width and height, optional thirds and center-line overlays, and a passepartout that draws black bars for framing visualization. One-click presets include 16:9, 9:16, 1:1, and 4:3. Safe areas provide Action Safe at a 90% default, Title Safe at an 80% default, and custom percentages.
Guides can use solid, dashed, or dotted line styles with per-guide RGBA color and adjustable width, and viewport display and render burn-in are controlled independently for each guide. Burn-in is non-destructive: it inserts guide nodes into your existing compositor at exact render resolution and cleans up when disabled, with a Regenerate button to refresh guides after changes such as a new resolution.
Camera Aspect Ratio Guides is best for cinematographers, motion graphics artists, and animators working across multiple aspect ratios and delivery formats, including broadcast and streaming work that relies on safe areas.
Camera Aspect Ratio Guides is completely free to download and use.
Camera Aspect Ratio Guides targets Blender 5.0 and later for this release. Once installed, its controls appear in the Camera Properties panel under a Composition Guides section, and that section is visible only while a camera object is selected. From there you enable the checkbox next to any guide to display it in the camera view through Numpad 0. Because it depends on a recent Blender version, check the developer's GitHub page before installing on an older build.
Camera Aspect Ratio Guides handles burn-in through the compositor. Enable a composition guide, safe area, or aspect ratio preset, then check "Burn into Render" for the ones you want in the final image and render with F12; those guides are composited automatically. The integration is non-destructive, inserting guide nodes into your existing compositor setup rather than replacing it, and it cleans up when you disable burn-in. A Regenerate button refreshes guides after changes such as a new render resolution. Only guides with burn-in checked appear in F12 renders.
Camera Aspect Ratio Guides lives in the Camera Properties panel, in a Composition Guides section that shows only when a camera object is selected. Select your camera, open that panel, and enable the checkbox beside any guide to see it in the camera view via Numpad 0. From the same place you can adjust colors, line styles, and widths, and toggle viewport display and render burn-in independently for each guide. Save your .blend file before rendering with burn-in enabled.
Camera Aspect Ratio Guides can display multiple aspect ratios in one view at the same time. Each preset supports custom width and height settings, along with optional thirds and center-line overlays per ratio and a passepartout that draws black bars for framing visualization. One-click presets cover 16:9, 9:16, 1:1, and 4:3. This lets you see how a shot reads across several delivery formats within a single camera setup.
Camera Aspect Ratio Guides is listed as free in this catalog and is distributed under the GNU General Public License v3.0 or later. Licensing terms can change, so check the developer's GitHub page for the current details before you rely on it in a project. The same page is where you can confirm version and compatibility notes. For reference, this entry documents version 2.0.0 with a recorded update in November 2025.
