1. What is Line Height?

Line height is the vertical distance between lines of text in typography. It's calculated by multiplying the font size by a multiplier value, typically between 1.2 and 1.5 for optimal readability.

2. How Does the Calculator Work?

The calculator uses the line height formula:

Where:

• \( Font\ Size \) — The size of the font in points (pt)
• \( Multiplier \) — A dimensionless value typically between 1.2-1.5

Explanation: The formula calculates the optimal spacing between lines of text based on font size and a standard readability multiplier.

3. Importance of Line Height Calculation

Details: Proper line height improves text readability, prevents text from appearing too cramped or too spaced out, and enhances the overall visual appeal of typography.

4. Using the Calculator

Tips: Enter font size in points and a multiplier value. Common multiplier values range from 1.2 to 1.5 for optimal readability.

5. Frequently Asked Questions (FAQ)

Q1: What is a good multiplier value for line height?
A: For body text, a multiplier between 1.2 and 1.5 is generally recommended for optimal readability.

Q2: Does line height vary by font type?
A: Yes, different fonts may require slightly different line height multipliers due to variations in x-height and character shapes.

Q3: How does line height affect mobile readability?
A: On mobile devices, slightly increased line height (1.4-1.6) often improves readability due to smaller screen sizes.

Q4: Should line height be the same for all font sizes?
A: Generally, larger font sizes may require smaller multipliers, while smaller fonts may need larger multipliers for readability.

Q5: Can I use this calculation for web design?
A: Yes, this calculation works for both print and digital typography, though web browsers may implement slight variations in rendering.
