PIXEL2PRINT • ADVANCED WEB MEASURE

Measure from a photo

Use a known-size reference in the same photo, calibrate the image, then mark the object dimensions. Results are estimates and depend on photo quality.

1. Take or upload a photo

Place a ruler or A4 sheet beside the object. Keep both on the same flat plane and photograph them straight-on.

Choose Open camera or Upload photo.

🧭 Straighten / Rotate photo

Adjust a tilted photo before marking measurement points.

Note: this rotates/straightens the whole photo. It cannot fully remove perspective distortion from an angled camera shot.
Step 1: add a photo to begin.

2. Calibrate reference

1
Enter the real distance between two visible reference points.

Example: use the long edge of A4 paper = 29.7 cm. Tap its two ends on the photo.

2
After calibration, tap two points for the object's first dimension, then two points for its second dimension.

🎨 Object color picker

Upload a photo, then click the color-pick button and tap the object area to sample its approximate color.

Photo colors are estimates. Lighting, shadows, camera processing, and screen differences affect RGB/CMYK values. CMYK shown here is a basic mathematical conversion, not a printer-specific color profile.

🛠️ Project tools

Zoom the photo for precise point placement. Save a project to reopen it later. Each saved measurement is kept in the history.

📐 Multi-object measurements

Use the calibrated scale from points 1–2, then add any number of object endpoint pairs below. Results are estimates on the same photo plane.

Upload a photo and mark the known reference first. Then add object pairs.
Perspective correction: true four-corner perspective warp is not included in this build. For best measurement results, photograph the reference and objects on the same plane with the camera parallel to it.
