Luminance Contrast Calculator
Luminance contrast is established when you compare the measurement of light reflected from one surface, compared to the light reflected from another surface. Light Reflectance Value (LRV) is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. Once you have the LRV of the two surfaces enter them below and our calculator provides the compliance answer.
Check Your Luminance Contrast Level
- Fail
-
30% (min) Luminance Contrast between:
- Integrated Tactiles and the installation surface
- Stair nosings and stair tread or top landing surface finish
- Visual contrasting strip on glazing and surface finish (within 2m of glazing)
- Door/wall/architrave luminance contrast (min. 50mm wide comparison)
- Pan seat and either wall or floor or pan
- Braille and tactile signage background and the installation location finish.
- Fail
-
45% (min) Luminance Contrast between:
- Discrete Tactiles and the installation surface
- Fail
-
60% (min) Luminance Contrast between:
- Composite Tactiles and the installation surface
Need Your Materials Tested?
Selecting materials based on appearance alone can be misleading. Architecture & Access offers in-house luminance contrast testing to help confirm that surfaces, fixtures and building elements achieve the contrast levels required for accessible design.
Want to better understand when high contrast improves accessibility and when it can create visual confusion? This practical CPD session explains the principles of contrast, common design mistakes, compliance requirements, and real-world examples of effective implementation.
