What is Line Height?
Line height is the vertical space between each line of text. When you increase line height, the lines spread apart more, giving text more breathing room.
For example, a paragraph with increased line height will have larger gaps between each row of text, making it easier to follow from one line to the next without accidentally skipping or rereading lines.
Who is This For?
This feature is helpful for:
- People with dyslexia who lose their place between lines
- Anyone who finds tightly packed text difficult to read
- People with visual stress or eye strain
- Students reading long articles or documents
- Anyone who wants text to feel less crowded

Step 6: Adjust the Height
Once Line height is turned on, a slider will appear below the toggle.
Drag the slider to the right to increase the space between lines. Drag it to the left to decrease the spacing.
The changes will apply to the website immediately, so you can see the effect as you adjust the slider.
Tip: Line height works great together with letter spacing and word spacing. If text still feels cramped after adjusting line height, try increasing the other spacing options too.
