High-contrast prints, sized for the eyes that will see them
Tell us who will be looking and how far away the picture will hang. We work out how big the pattern has to be for them to actually see it, and give you a sheet to print at home. Free, for any age, and it never leaves your browser.
First time printing? Check your printer once — print one sheet at 100% and measure the bar — and every card after that comes out the right size.
Who it's for
Typical and premature infants, children and adults with low vision or CVI (cortical/cerebral visual impairment), older children, and vision-therapy or sensory contexts.
How it works (and what it isn't)
- Runs entirely in your browser. No accounts; images you upload never leave your device.
- Exact physical scale. The file is exact at 100% / actual size. Cards print clean — check your printer once and every card after that is right.
- Not a medical device. It's an informed enrichment / accessibility tool, not a diagnostic or therapeutic one. For premature, CVI, or low-vision care, follow your clinicians.
Works offline too: add it to your home screen or desktop and, after the first visit, make cards with no connection at all. The research behind every design choice is on the blog.
