X-Height Basics

Definition

You should know what x-height means before making road signage. X-height is the space from the bottom to the middle of lowercase letters. People use the letter ‘x’ to measure this space. On road signage, x-height shows how tall lowercase letters are next to uppercase ones. This helps keep letters clear and easy to read.

• X-height is very important in sign design.
• Designers check the height of letters like ‘a’, ‘e’, and ‘s’ to keep words clear.
• You must not stretch or squash letters, or the sign will be hard to read.
• Marks like dots or accents must also be easy to see from far away.

For signs facing oncoming traffic, the minimum x-height ranges from 20 мм до 40 мм. On roads where the 85th percentile speed is above 40 миль в час, you should use the maximum height of 40 мм. For roads with lower speed limits, а 20 mm x-height is usually enough. The table below shows how x-height changes with speed and sign type:

Mounting and Materials

All signage must be free from obstructions like trees or parked cars.

Кончик: Use certified reflective materials and keep records of all planning and maintenance checks.

You should carry out site checks in both day and night conditions. Ночью, use the Visual Nighttime Inspection Method. During the day, use a retroreflectometer to measure reflectivity. Always plan for regular cleaning and maintenance to keep your signage clear and safe.
