# Print doesn't fit (size / build volume): a queue size mismatch

# Print doesn't fit (size / build volume): a queue size mismatch

A free printer skipped your queue item, and the queue inspector says the print is too big for the build volume - it's a quick fix.

## What this means
SimplyPrint uses **tags** to route the right files to the right printers - so a job only runs on a printer that can actually print it correctly, and you don't waste time and filament printing something on the wrong setup. A file or queue item can be tagged with details like its material, color, nozzle size and bed type, and SimplyPrint also checks things like whether the model fits and whether the printer can run the file. When a printer doesn't meet one of the item's requirements, the two won't match, and the item won't start on that printer.

In this case, it means the object is larger than the printer's build volume, so it physically can't print there. This check also covers needing more extruders or tool positions than the printer has.

## How to fix it
- Send the item to a printer with a big enough build volume.
- Or scale the model down and re-slice, if that's acceptable.
