Hi all,
Katheryn from the Bike Kitchen in Windsor, Ontario here! Question for the community shop hive: does anyone have any ideas for effective and accurate systems for sizing wheels in your shop? We’ve got piles of used wheels with no markings or tires to identify them with that often get mislabelled (most commonly a 700c and 27x1 1/4 mixup) which is causing issues when we resell them.
Does your shop have a sizing system that is easy to use for students or volunteers without much technical knowledge to size and sort wheels with? Pictures would be appreciated if you’ve got a physical setup.
Thanks in advance!

From my time at the Columbus, IN Columbus Bike Co-op:
2 2 x 4s mounted to a wall in a V-shape. Between the 2 x 4s, the axle location for each size noted and labeled in paint. Wall was cinder block in a basement, so no concern about damage from the axles hitting the wall.

We also have a handy dandy wheel sizing chart -- the idea is to tag all the wheels, rims, and tires in the shop with the appropriate colored tape. For the most part we use non-adhesive flagging tape, to not leave a residue. All the colors in the chart are available at zoro.com in flagging tape and electrical tape too. (The red-with-a-dot is to help folks who can't see a full spectrum of colors -- you can just add a dot to the red tape you find.)

Simple but effective. Not my design, easy one to steal! The key is the little half blocks that align the rim without the axle bumping the backboard. No real need to measure anything, just make it wide enough to fit your wheels. Then use known reference wheels (no tires) to mark the backboard. 10 min project!

We use (true) rims marked with their sizes: you hold the "sizer" rim against the one to ID with both hands on opposite sides, and if they are not the same you will feel the difference, down to the smallest variance (584 to 590 BSD). This will even detect rims that are nominally the same but not exactly (one factor in the mysterious "tight fitting tire syndrome"). Works with a tire still mounted on the target wheel, with practice. We tie a "sizer" rim to each corresponding section of the wheel room to check before hanging, and double check before choosing.
