Calculate total image height, text height, or text-to-image ratio from two values in pixels and percent with this text to image ratio calculator.
Text To Image Ratio Formula
The text to image ratio compares the total height of text in an image to the total height of the image. The result is shown as a percentage.
- Text To Image Ratio is the percentage of the image height occupied by text.
- Total Text Height is the combined vertical height of the text, measured in pixels.
- Total Image Height is the full height of the image, measured in pixels.
Select the value to solve for, then enter the two displayed known values. Measure text and image heights in the same pixel coordinate system. Image height must be positive; text height and ratio may be zero. Solving image height requires positive text height and ratio.
Common Text Coverage Percentages
These informal descriptions compare vertical heights, not image surface area or advertising-policy limits.
| Text To Image Ratio | Meaning |
|---|---|
| 5% | Very little text. Usually a small caption, label, or logo text. |
| 10% | Light text coverage. Often used for simple banners or social graphics. |
| 20% | Moderate text coverage. The text is clearly noticeable. |
| 30% | Heavy text coverage. The image may start to feel text-dominant. |
| 50% | Half of the image height is text. This is a very text-heavy layout. |
Pixel Examples By Image Height
This table shows how many pixels of text height match common ratios.
| Image Height | 10% Text Height | 20% Text Height | 30% Text Height |
|---|---|---|---|
| 600 px | 60 px | 120 px | 180 px |
| 800 px | 80 px | 160 px | 240 px |
| 1080 px | 108 px | 216 px | 324 px |
Example Problems
Example 1: Calculate the text to image ratio
You have an image that is 800 pixels tall. The total text height is 160 pixels.
The text to image ratio is 20%.
Example 2: Calculate the total text height
You have an image that is 1200 pixels tall. You want the text to image ratio to be 15%.
The total text height should be 180 pixels.
FAQ
What does text height mean?
Text height is the vertical space taken up by the text in the image. If the image has several lines of text, use the combined height of all text lines and the space between them if that space is part of the text block.
Can the text to image ratio be more than 100%?
For one contained text block, the height ratio is at most 100%. A larger ratio is mathematically valid but means the supplied text height exceeds image height; check the measurements or whether multiple overlapping blocks were summed.
Should I use image width in this calculation?
No. This calculator uses height only. It compares total text height to total image height. It does not measure text area, image width, or the percentage of total image surface covered by text.
