Starting points, not fixed catalogue sizes — every size can be adjusted.
Logo size that fits each bag
A logo usually looks best at about 60% of the panel width and half its height. Approximate maximum print areas:
Seams, pockets, flaps and handles reduce the usable area; we confirm the exact print size on the artwork proof.
How bag sizes are measured
Width (W)
Measured across the front panel, seam to seam, at the base.
Height (H)
Measured from the base to the top edge of the bag — handles are not included.
Depth / gusset (D)
The width of the side and base panels. A deeper gusset lets the bag stand up and hold boxes.

- Pre-primary: choose it for tiffin, bottle, a few books
