What size should a guinea coop door for them to enter into the coop?

We recently moved our guineas to their new fly pen with a storage building for a coop with a small door for them to enter and exit. What size should this door be and do they need a ramp for it? Thanks so much.

My pop door for my hens and rooster is 9w"x12h". This Delaware rooster fits through with no problems.
If you need a ramp it is good to make the length of it twice the drop is a good rule of thumb.
This will give it a 6/12 pitch if you place a 4 or 6"block at the ground end it will even be a gentler slop.

I'm sorry, but what's a "pop door"?

The opening in this photo the hens would employ to get in and out of the chicken coop.
