# Sage_GuessResolutionByRatio
|
|
|
|
## Guess Resolution by Ratio
|
|
|
|
Analyzes input dimensions and suggests the closest standard resolution from common aspect ratios, rounded to multiples of 64.
|
|
|
|
## Inputs
|
|
|
|
### Required
|
|
|
|
- **width** (INT): Input width dimension (range: 64-8192)
|
|
- **height** (INT): Input height dimension (range: 64-8192)
|
|
|
|
## Outputs
|
|
|
|
- **width** (INT): Suggested width dimension
|
|
- **height** (INT): Suggested height dimension
|
|
|
|
## Usage
|
|
|
|
Based on the input width and height, this node guesses a resolution that matches one of the common aspect ratios. The output is rounded to the nearest multiple of 64.
|
|
|
|
## Notes
|
|
|
|
- Supports 11 common aspect ratios including 1:1, 5:12, 9:16, 10:16, 5:7, 2:3, 3:4, 4:7, 7:9, 8:10, and 13:19
|
|
- Automatically detects landscape vs portrait orientation
|
|
- Finds the closest aspect ratio by comparing input ratio to predefined ratios
|
|
- All outputs are rounded to nearest multiple of 64 for optimal AI generation
|
|
- Swaps dimensions appropriately to maintain landscape/portrait orientation
|
|
- Defaults to 1024x1024 if no close match is found
|
|
- Useful for standardizing arbitrary input dimensions to known good ratios
|
|
- Optimized for AI image generation workflows requiring specific aspect ratios
