SEC Storage have created a Ratio Test, a simple and quick method of identifying whether the pick-faces in your warehouse are too large. Using a few simple metrics, we can calculate a ratio that shows how well-balanced replenishment frequency and travel distances are within your warehouse.

To help explain how it works a bit further, we’ve created a short video explainer that should give you everything you need to know.

And once you understand how it works, you can use our quick calculator below to determine whether your pick-faces are oversized.

The Ratio Test Explained

In the video below, we explain a little more about the ratio test and how it works.

NOTE: Unfortunately, the video is currently down to be tweaked, it’ll be back up shortly though.

What does your score mean?

50% or more

If your score is 50% or more then your pick-faces might be too small


If your score is 25-50% your pick-faces are probably right-sized


If your score is 12.5-25% then your pick-faces are probably too big


If your score is 12.5% then your pick-faces are very likely to be too big
