Derby Plate Sizing Instructions

Plate charts can be straight forward when choosing a boot and plate within the same brand, but can get trickier when trying to mix and match. The best option when crossing boot and plate brands is to base your sizing off of the current wheelbase of your plates.

To get the wheelbase of your current plate, you will need to measure your assembled plate from the middle of the rear axle to the middle of the front axle in millimeters and inches.

If you do not have a current plate to compare or you are changing the size of your boot, you can also use the charts below. Simply click the brand of your boot and use the chart to find the recommended wheelbase. Use this number to compare to the brand chart for your plate of choice. This will not be as accurate but will still work in most cases!

Once you have this measurement, click a brand below to view the corresponding sizing chart.

If you are having trouble sizing, please contact us at 800.366.3070 or info@derbywarehouse.com.

NOTE: Plate sizing for Bont boots typically needs to be adjusted from the recommendations below. Please contact us for sizing if mounting to Bont boots.

Chaya Plate Sizing

Chaya plate sizing will vary depending on if you are mounting them to Chaya Boots or another brand due to the unique Dual Center Mounting technology. For the best results, size these plates as follows:

Chaya Boots to Chaya Plates: Refer to the "Chaya Skate Size" column on the corresponding 20° or 45° sizing chart to ensure that DCM works properly.

Other Boots to Chaya Plates: Use your current plate's wheelbase as reference to find the most similar Chaya Plate size in either 20° or 45°.

If replacing a Chaya Plate with another brand, use the wheelbase listed on the 20° chart as reference for finding another plate, even if you have currently have a 45° plate installed.
