Copying a photograph by hand goes wrong in the same place every time: not in the shading, but in the layout. An eye lands a few millimetres too far left, a roofline sits too high, and by the time it is obvious the drawing is too far along to rescue.
The traditional fix is to rule a grid over the reference and a matching grid over the paper. It works, and it means drawing all over both. MeasureOver does the same job without the pencil work. Drop guide lines onto the photo on screen, and every place two of them cross is reported as a real measurement on the sheet in front of you — 84.2 mm in, 120.5 mm down. Mark those points and the proportions are already correct before a single line is drawn.
It is useful anywhere a reference has to become a physical drawing at a known size: portraits and figure work, stencils and sign painting, pattern drafting, marquetry and inlay layout, murals scaled up from a small study, and transferring a design onto a workpiece before cutting.
Drag an image in or pick a file. It is decoded in your browser — nothing is uploaded to a server, so there is no wait and no account.
Click once in cross mode to drop a paired horizontal and vertical guide. Line mode places a single guide between two points, and the edge handles slide a straight guide in from any side. Every guide extends across the whole image.
Wherever two guides cross, MeasureOver reports that point in millimetres, centimetres or inches — measured against the paper size you picked, not against pixels.
Export a 300 DPI PNG with the guides burned in and print it at your paper size, or keep the numbers on screen and mark the same points on your sheet by hand.
Coordinates are calculated against the exact dimensions below, so switching size re-measures the whole image instantly. The last column is what a 300 DPI export produces for that sheet.

Measurements display in millimetres, centimetres or inches — the unit changes how the numbers are shown, never the underlying geometry.
There is no upload step, because there is no server to upload to. MeasureOver is a static page: the image is decoded, measured and exported by your own browser and never crosses the network. That means no account, no storage limits, no cookie banner, and no question about who else can see a client's reference photograph.
Saved projects — your guide lines, paper size and settings — are kept in your browser's local storage on that device only. Once the page has loaded you can go offline entirely and it will keep working. The only third-party script on the site is a privacy-preserving page-view counter that sets no cookies and collects no personal data.
