📖 Practical Techniques for Adjusting Line Height
The line-height property is a crucial factor in determining text readability. Proper line height settings improve users’ reading speed and comprehension.
📊 How to Choose the Optimal Line-Height Value
Generally, for Japanese text, a value between 1.6 and 1.8 is considered optimal. For example, 1.8 is suitable for body text, while 1.4 can be used for headings. For mobile displays, increasing to around 2.0 makes text easier to read on smaller screens.
✨ Advanced Techniques
Instead of a unitless relative value (e.g., 1.8), specifying line height in rem units maintains balance when font sizes change. Also, using the calc() function like line-height: calc(1em + 0.8rem) allows precise control of the baseline spacing.
⚠️ Cautions and Best Practices
Too large a line height (above 2.5) can make text harder to read. For multi-line linked text, be careful not to make the clickable area excessively large. In responsive design, use media queries to set optimal line height according to screen width.
Consistent line height across the site is important for design unity. However, for special content such as poetry or quotes, intentionally using different values can be effective.
