Check a true 4 × 6 inch label setup.
Four by six inches is 101.6 × 152.4 mm. Start with the matching PDF, then check whether the viewer and driver preserve those dimensions on paper.

MADE FOR THE FLOOR
For teams using 4 × 6 inch label stock and checking page size, orientation, clipping or unexpected scaling.
A USEFUL STARTING POINT
Similar stock sizes need different PDFs
A 100 × 150 mm page is not the same size as a 4 × 6 inch page. PrintBench includes both as separate fixtures. Selecting a nearby size or allowing fit-to-page can change the output even when the document looks correct on screen.
FROM QUESTION TO EVIDENCE
Three steps to a useful result.
- 01
Select 4 × 6 inches
Choose the 4 × 6 profile in PrintBench and the appropriate 203 or 300 DPI fixture. Check the stock specification rather than relying on a queue's friendly name.
- 02
Match the viewer and driver
Set 4 × 6 inch paper dimensions, intended orientation and actual size or 100%. Print one copy and confirm the fixture identifier on the resulting label.
- 03
Check both axes
Measure the horizontal and vertical reference marks between tick centres. Record clipping or rotation separately. Then compare scanner input against the known Code 128 or QR value.
A screen preview cannot confirm physical size
A PDF viewer can make different page sizes appear equally large on screen. The document's dimensions, the selected driver stock and the marks measured on paper provide different pieces of evidence. Record them together before changing another setting.
BEFORE YOU START
A few practical answers.
Can I use the 4 × 6 test on 100 × 150 mm stock?
Choose the dedicated 100 × 150 mm fixture instead. Using a different-size page introduces another variable and can lead to fitting, clipping or scaling.
Does the 300 DPI choice change the page size?
No. Both fixtures retain the selected physical page dimensions. Resolution changes the source dot grid, including the realized lengths of reference marks.
Does a successful scan mean the setup is correct?
It means the received text matched the expected payload for that observation. Page size, scaling, print appearance and barcode quality require their own checks.
What are the current limits?
This is a software-tested alpha; physical printer, driver and scanner combinations are not yet qualified. PrintBench does not connect directly to printers, inspect queues, calibrate hardware, grade barcodes, design custom labels or discover printer DPI. Its fixtures cannot check the size of FactoryCards' 100 × 50 mm cards.
What happens to my data?
Measurements, notes and scan values stay in browser memory. No account, uploads or tracking scripts are required. Test PDFs and preview assets load from this site. Downloaded reports are redacted by default; review before sharing. Reloading loses the session. Hosting may log ordinary requests.
