Finally, what is the maximum length we can use for our URLs/Slugs? According to the test we have ran below, the URL started to be trunked at 371px.

However, this URL include folders (silo), which could be treated differently. Now let see how the flat rate URLs are treated now.

So according to the test above, a flat URL without sub-folders (silo category) is trunked at 437 pixels.
