Setting the Standard: Universal Size Chart

Over the years, climbing hold brands have created multiple ways to categorize the size of a single hold or sets of holds. As industry trends change, these metrics must also change (i.e., what was a “large” in 2008 is now a “small” in most lines).

With this in mind, we have created a universal sizing system for all climbing holds. The goal of this system is to give routesetters a resource to help compare size and value across any climbing hold brand. In addition, the chart incorporates both Imperial and Metric sizing units.

How to use it:

Step 1: Place the hold in the center of the size chart.

Step 2: Determine the appropriate size ring.

The thickness of the red rings represents the difference between Imperial (US) and Metric sizing.

For Imperial sizing, all parts of the shape must fit ENTIRELY within each ring and not overlap into the red. If any part of the hold passes into or beyond the red, the shape is considered to be in the next larger size ring.

For Metric sizing, parts of the shape can overlap into, but not beyond the red rings.

To determine the size of a SET, measure each shape individually and calculate the average size of all holds within that set.

Why use it?

Each company has its own proprietary sizing metrics which are not relevant to other companies or countries. Many companies have also seen their sizing become less relevant as hold sizes overall have increased.

We created this sizing system so that routesetters have a universal tool to help sort inventory, determine gaps in hold size offerings, and to help guide purchase decisions.
