Plate Sizing Guide
How To Choose Your Plate Size
Pilot Falcon plates are sized by their wheelbase, measured in inches. The wheelbase is the distance between the center of the front and rear axles.
To determine your ideal size:
-
Identify your boot. Know the brand, model, and size of the boot you're mounting.
-
Measure your current wheelbase. If you're replacing an existing plate, measure from the center of the front axle to the center of the rear axle.
-
Consider your mounting preference. A shorter wheelbase typically offers quicker maneuverability, while a longer wheelbase generally provides more stability.
-
Compare your measurements with the chart below. Remember that plate size and boot size are not interchangeable.

Viper-Specific Tips
-
Falcon upgrades: The Pilot Viper and Falcon use Pilot's universal mounting system, which is designed to allow upgrades without drilling new mounting holes when the plate sizes and mounting pattern are compatible.
-
Wheel clearance: Wheel compatibility can vary by plate generation. Check clearance before using smaller-diameter wheels, particularly on older Viper plates.

Tracer-Specific Tips
-
Bont boot sizing: Use your actual Bont boot size, not your regular US shoe size, when referencing the recommended sizing charts.
-
Different boot models: Bont's plate recommendations vary depending on the boot. The manufacturer also publishes separate charts for Racer and Spin boots.
-
Other skate brands: If mounting Tracers onto Antik, Riedell, or another boot brand, compare wheelbase, overall plate length, and intended axle placement rather than using the Bont boot-size recommendations.
-
Mounting hardware: Mounting hardware is not included with the Tracer plate and must be purchased separately.
POWERDYNE REACTOR PRO PLATE

Reactor Pro-Specific Tips
-
Riedell boot sizing: The recommended boot sizes are based on Riedell sizing, not standard US shoe sizes.
-
Other boot brands: When mounting onto Antik, Bont, or other brands, use wheelbase and plate length to help determine the appropriate fit.
-
Plate length: Overall plate length includes the baseplate beyond the front and rear axles. This matters when checking available mounting space.
-
Mounting preference: Skaters who prefer a shorter or longer wheelbase may choose a different plate size than the manufacturer's standard recommendation, provided the mounting is appropriate for the boot.
SURE-GRIP AVENGER ALUMINUM & MAGNESIUM PLATES
The Sure-Grip Avenger Aluminum and Magnesium plates use the same sizing system, with numbered plate sizes and wheelbase measurements in millimeters.
Avenger Plate Sizing Chart
| Plate Size | Wheelbase (mm) |
|---|---|
| 0 | 130 |
| 1 | 140 |
| 2 | 150 |
| 3 | 160 |
| 4 | 170 |
| 5 | 180 |
| 6 | 190 |
| 7 | 200 |
| 8 | 210 |
Avenger-Specific Sizing Tips
-
Short-forward mounting: The Avenger is popular for short-forward mounting, where the front axle is positioned near the ball of the foot and the rear axle farther forward than in a traditional mount.
-
Traditional mounting: A standard mount is also possible, but may require a different plate size than a short-forward setup.
-
Boot sizing: Sure-Grip's recommended boot sizes are based on its own boots. If you're mounting onto Antik, Riedell, Bont, or another brand, compare wheelbase and intended axle placement instead.
-
Aluminum vs. Magnesium: Both versions share the same sizing measurements. The primary difference is the baseplate material and weight.
SURE-GRIP AVANTI MAGNESIUM PLATE
The Sure-Grip Avanti Magnesium uses numbered plate sizes from 1–9. The chart below includes the manufacturer's recommended boot sizes and wheelbase measurements.

Avanti-Specific Sizing Tips
-
Boot recommendations: The suggested boot sizes are approximate. Always compare the wheelbase and actual boot dimensions before selecting a plate.
-
Mounting options: The Avanti features multiple front mounting holes to accommodate different boot styles.
-
Plate length: Overall plate length is different from wheelbase. Consider both measurements when determining compatibility with your boot.
-
Park skating: If using slide blocks or wide trucks, verify accessory compatibility with your selected plate size before purchasing.

-
Replacing an existing plate: Check your current plate size and wheelbase before ordering.
-
Custom mounting: Confirm the plate's overall length, wheelbase, and intended axle placement when mounting onto another boot brand.
-
Rock vs. Probe: Although both use numbered sizes 1–9, their recommended boot-size charts are not identical.
CRAZY SKATES APOLLO PLATE
The Crazy Skates Apollo uses millimeter-based sizing. Each plate is identified by its overall plate length and axle spread (wheelbase), measured from the center of the front axle to the center of the rear axle.
Apollo Sizing Chart

Apollo-Specific Sizing Tips
-
Plate length vs. axle spread: Crazy Skates identifies each Apollo size using two measurements. Make sure you're comparing the correct numbers when selecting your plate.
-
Boot compatibility: Compare the plate length to the available mounting area on your boot and check the axle spread against your preferred mounting position.
-
Similar sizes: Some Apollo options have nearly identical measurements, such as the 225mm and 226mm plates. Double-check the exact size before ordering.
-
Replacing an existing plate: Measuring your current axle-to-axle distance is a helpful starting point when choosing an Apollo.
-
Custom mounting: Different boot brands and mounting preferences may require a different plate length or axle spread than your existing setup.
