Reading Ruler for Dyslexia
Some people with dyslexia find it difficult to keep their place when reading, particularly when text is dense or lines are close together. A reading ruler can provide a visual guide across the line and may make it easier to follow text without repeatedly losing your place.
A reading ruler is a reading aid, not a treatment for dyslexia. It will not be helpful for every reader, but it is simple to try alongside other reading support.
Reading Rulers for Visual Stress
Some readers experience visual discomfort when looking at blocks of text. Coloured overlays or tinted reading rulers are sometimes used as a reading aid. There is no single colour that works for everyone, which is why this tool lets you try different colours and adjust the strength.

Reading Ruler for Children
A reading ruler can be useful for children who lose their place when reading stories, homework or longer passages. Let the child try the different colours and settings rather than assuming one particular colour will work best.
Digital Reading Ruler vs Physical Reading Ruler
A physical reading ruler can be useful with printed books and worksheets, while a digital reading ruler is useful when reading on a screen. If you regularly switch between paper and digital reading, you may find it useful to have both.
Printable Reading Rulers
If you are looking for a printable reading ruler, a physical coloured ruler can be placed across a printed page. This online tool is intended for screen reading and gives you adjustable colour, height and strength without needing to buy or carry a physical ruler.
Do Reading Rulers Work?
Reading rulers can be useful for some readers, particularly when the main difficulty is keeping track of lines or when tinted colour makes text more comfortable to look at. They are not a cure for dyslexia, and research into coloured overlays and visual stress is mixed. The simplest approach is to try the tool and see whether it makes reading more comfortable or easier to track.
Reading Rulers in the Classroom
Reading rulers can be a simple classroom reading aid for children who lose their place in dense text. A digital ruler can be used on a class tablet or computer, while a physical ruler can be used with printed books and worksheets.
