The problem with "dryfitting" PVC fittings is that if you push them tight they are extremely difficult to pull apart when you want to prime and glue them and if you don't push them together you can't get a accurate measurement.
The reason for this is that the female side of the hub has a slight taper that almost locks the two when shoved together without the lubricating application of the glue.
Some of us get around this by laying the PVC fittings next to each other and getting a measure that way while some of us push the fittings together until they start to bind up and measure the distance between the male section and where it would butt up with the hub. We can then subtract the added measures and get a fairly accurate overall measure. There are drawbacks as well as advantages to working with plastic but the advantages far outweigh the drawbacks. Good luck, Tom
