Victorian certified seed potatoes are usually sold by their dimensions - measured in millimetres. Prior to sale, certified seed is graded according to size with the help of a sizing template. 

The SPV Field Sizing templates are made from moulded industrial grade plastic and are a set of 13 individual templates that are bolted together, ranging from 30 to 90 mm that cover both seed and commercial sizes.

The template set can be ordered below online. The field templates are $77 for the set (inc GST). Postage is a flat $18 inc. GST
