Typical rookie here,
I just now noticed that one of my hives has a larger or "taller" entrance slot than the other. The hives are different and each came from a different supplier. It might be I have one bottom board upside down.
How tall should the entrance opening be?
-
Mine are all supposed to be 3/4", give or take a 1/16". I've had sand a couple of my blocks to get them to fit because they were a little tight.

Most of the 19th century literature recommends MUCH smaller openings than we currently use - in most cases a 1"-2" hole. Most "feral" hives will seek cavities with pretty small entrances, too.
My Warre hives seem to have no more difficulty using their 1/2" x 4" openings than the full-width x 5/8" openings of my Langstroth hives.

Being in SHB territory I keep my entrances as small as the hive allows me to. 3/8" high by what ever can be guarded by the bees.. a single deep is at the moment about 7-8" long

Mine are all 3/8". It works well for me. I also notice that I never get much debris build up in the winter as I used to have with 3/4". The bees keep it cleaned out.
In the summer, I slide a super above the hive bodies back about 3/8" for an additional entrance when needed.
In the winter, I fasten a reducing block to the bottom so that the bottom entrance is about 3/4" wide, and keep a 3/4" round hole near the top of the hive open.

Between 1/4" and 3/4"

about 3/8"

I am in Central FL....it's starting to get warm. I have my hive in a spot that is shaded late afternoon, which I hope will help. My entrance is 3/8" and I was thinking of making it larger until I found this post. This is a package that was installed about 49 days ago, 3.13.13. There are a lot of bees at the entrance...cleaning and fanning. I don't see any dropped pollen but there is definately a traffic jam. Do you leave yours 3/8" all year round?

FYI we are talking height and not length. I suspect you would need to open your entrance reducer a bit, not increase the height of your entrance.
My entrances are 3/8" tall.
