My regular WERMK punch board goes from card size 2 x 3 1/2 up to 6 x 8 1/2. Score lines from 2 to 4 1/8
My mini punch board goes from card size 1 x 1 to 4 x 4. There are some duplicates in both from the range of 4x4 to 2 1/2 x 3. The smallest score line is at 1 inch and largest score line at 3 1/8 inch
It's about the size of the printed chart on the regular punch board, approximately 6 3/4 by 3 3/4
The mini allows you to cut card size envelopes that are smaller than 2 x 3 1/2, an additional 10 cards of smaller sizes.
You will find that the numbes on the mini are a larger font and can be read better than the chart printed on the regular board.
This mini punch board is a cutie!.
