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.
To calculate the text to image ratio, enter the image height and text height. To calculate text height, enter the image height and ratio. To calculate image height, enter the text height and ratio. Leave exactly one field blank.
Common Text Coverage Percentages
Use this table to understand what different text to image ratios mean visually.
| 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%?
In normal use, it should not be more than 100%. A ratio above 100% means the text height is greater than the full image height, which usually means one of the measurements was entered incorrectly.
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.
