Calculadora de Interlineado — Espaciado de Línea Óptimo Online Gratis

Line height is one of the most impactful yet overlooked typography settings. Too tight and text feels cramped; too loose and paragraphs fall apart. Nuestro/a Line Height Calculator provides optimal values based on font size, line length, and typographic best practices, giving you the exact CSS values to use.

¿Qué es Line Height?

Line height (or leading) is the vertical distance between baselines of consecutive lines of text. In CSS, it is expressed as a unitless ratio (e.g., 1.5), a pixel value, or a percentage. The optimal line height depends on font size, line length, and the font's x-height — there is no single "correct" value.

Cómo Usar Nuestra Line Height Calculator

1. Enter ynuestro/a font size in pixels, rems, or ems.
2. Specify the approximate line length (content width) if known — this affects the optimal line height.
3. The calculator provides recommended line height values with a live text preview.
4. Copia el/la CSS value and apply it to ynuestro/a body text, headings, or specific elements.

¿Por Qué Usar Line Height Calculator?

• Readability: Correct line height significantly improves reading speed and comprehension, especially for long-form content.
• Responsive design: Different screen widths need different line heights. Narrower columns need tighter line height, wider columns need more.
• Professional polish: Proper line spacing is subtle but immediately distinguishes professional design from amateur work.
• Accessibility: WCAG recommends a line height of at least 1.5 for body text to aid users with reading disabilities.

Casos de Uso Comunes

Web designers fine-tuning body text readability on content-heavy sites — blogs, news sites, documentation — use line height calculators to find the sweet spot where text is comfortable to read for extended periods.

Email developers adjust line height for different email clients, which render text with varying default spacing. A calculated value ensures consistent appearance across Gmail, Outlook, and Apple Mail.

Print designers converting designs to web need to translate their leading values (measured in points) to CSS line-height values (unitless ratios), accounting for the different measurement systems.

Consejos y Buenas Prácticas

• Use a unitless line-height value (e.g., line-height: 1.5) rather than pixels or percentages. Unitless values scale proportionally with font size.
• Body text typically needs a line height of 1.4-1.6. Headings need tighter spacing (1.1-1.3) because they have larger font sizes.
• Wider line lengths need greater line height. If ynuestro/a content area is 800px wide, use 1.6+. For narrow columns under 400px, 1.4 may be sufficient.
