Click any preset and Blender's output resolution changes instantly.

Instant Aspect Ratio also automatically sets Blender's Resolution Percentage to 100%, ensuring the final render uses the displayed resolution.

Swap Orientation

Click Swap Orientation to instantly switch the width and height.

For example:

1920 × 1080 → 1080 × 1920

This is useful when converting between landscape and portrait formats.

Resolution Multiplier

After selecting a preset, you can increase its resolution using:

1.5× | 2× | 4×

For example:

1080 × 1920

2× → 2160 × 3840

Multipliers always calculate from the original selected preset, so they do not stack accidentally.

Use Revert Scale to return to the preset's normal resolution.

Favorites

Click the star icon beside any preset to add it to Favorites.

Open the Favorites category to quickly access all of your most-used formats in one place.

Click the star again to remove a preset from Favorites.

Custom Presets

Instant Aspect Ratio can also save your own resolutions.

1. Manually set the Resolution X and Y you want.

2. Open Custom.

3. Click Save Current Resolution.

4. Give the preset a name.

5. Click Save.

Your custom format will now appear inside the Custom section.

Custom presets can also be:

• Added to Favorites

• Used with resolution multipliers

• Swapped between portrait and landscape

• Deleted when no longer needed

Custom presets and Favorites are saved in the addon preferences, so they remain available across different Blender projects and after restarting Blender.

Restore Original

Instant Aspect Ratio remembers the resolution your project was using before you first changed it.

Click Restore Original to return to that resolution.

This is useful when experimenting with different formats without losing your project's previous settings.

Blender Default

Click Blender Default to quickly return to:

1920 × 1080 at 100%

That's It

Instant Aspect Ratio is designed to stay simple.

Choose a category → choose a format → render.

No calculators, no repeatedly typing resolution values, and no searching online for common image sizes.
