A reading exists but nothing corroborated it. The amber edges are the ones worth checking.
Can the card be told apart from the surface behind it? Everything downstream rests on this one test, so it is worth a look before trusting any number. This stage is a property of the photograph — it does not change when you move a handle.
- measurement methods disagreed by 6 percentage points on the centering ratio

Put each corner on the card's physical edge. Tap one to select it, then move it with the pad below. The flattened card re-renders as you go, so step 3 always works from what you set here.
move the selected handle
selected
Tap a handle to pick it, then move it from here — nothing covers the line. Dragging any empty part of the image moves the selected handle too. Arrow keys work the same.
selected corner (px)
Pick a corner on the image to type its position. Blank means nothing is selected.
move all four together
A tilted photo is one rotation, not four corner errors — fixing it here is one number instead of four chances to get it wrong. Expand pushes every corner outwards at once, for a box that sits just inside the card all the way round.

your own card
Your own card. Auto has not seen it, so every handle starts as a scaffold — the grade stays blank until you place the border.
Measure a card of your own. Nothing is uploaded — the photo is read in this browser, and it stays on this device unless you download the correction file yourself.
Choose a photo first — there is nothing to measure yet.
a photo worth measuring
- Shoot square-on. A tilted shot is correctable in step 2, but every degree you fix by hand is a degree you can get wrong.
- Put the card on a surface that is not its own colour — a dark desk under a rainbow card is the single biggest cause of a bad reading.
- Fill the frame, but keep all four edges and a margin of desk visible.
- Flat, even light. A glare band across a border hides where it ends.
what this can and cannot tell you
It measures centering — the four border widths and the ratios PSA grades them on. It says nothing about surface, edges or corners, and a card can be perfectly centred and still grade 7.

precision
Click a corner to select it, then ←→↑↓ to nudge 1 px, or shift + arrow for 10. ctrl + scroll zooms on the pointer.
Tap a handle to select it, then move it with the pad below — your hand never covers the line. Round handles move one edge; square corners move two.
move the selected handle
selected
Tap a handle to pick it, then move it from here — nothing covers the line. Dragging any empty part of the image moves the selected handle too. Arrow keys work the same.
border widths (px)
Type a value when you know it. A corner handle moves both of its edges together.

Auto could not read this card's border. Go to step 3 and place the four handles — until then there is no measurement to report.
keep this reading
Saving keeps your work on this device. Download correction writes a file carrying the corrected geometry, the photo and what auto had said — commit it and the scanner can be replayed against your judgement, which is the only way a manual fix ever improves the automatic reading.
share it with everyone
Publishing puts this grading — including the photo — in the shared gallery on this site, where anyone who visits can open it and check your placement. Saving above keeps it on this device; this does not.
