on the small door, what are the dimensions of the door opening itself.

I believe if you look at the product details it lists the dimensions for each size.

It's about 18 inches deep with door open. 21 inches wide with door open. And approx 50 inches tall on the inside.

If I remember correctly, it is about 1 and 1/2 inches. It fit my standard door perfectly.

The opening is 18" tall by 13" wide. This door is excellent. We have had an extremely cold winter with a lot of wind and never once have we felt a draft. I would highly recommend this door!

The actual opening is a little over 7" wide and the height opening is a little over 8". I was worried about the size too, when I bought it, but it's been perfect! I have a 23 lb. dog who zooms right through. Be very careful when you install it, though! It has to be very close to the bottom of the door, or the dogs won't be able to activate it with the chip or the collar tag. Otherwise, this is one of the best products I've purchased in a long time! I love it! Hope this helps - Cheri W.

It fit through my door barely, but it did. If it doesn't you can just take the pieces in separate. Don't remember the exact dimensions, but it's not huge.

Overall opening is 27 3/4 inches wide & 19+ inches high. Each door is approximately 13 3/4 inches wide by 19" high. As a note, if you get this be careful not to put the screws (that hold the small square metal pieces on the doors, top & bottom doors) that catch the magnets into the corner of the doors very tight as they will poke through the face of the doors leaving marred finish on face of doors.

A little over a foot long (about 15 inches I'd say) and about 1-2 inch wide. It's a great little item and the USB ports are an added benefit. You have to be used to flipping the doors but its not too hard to figure that out heh. Hope this helps.

There are two different openings, one is about 4"x4" and the other is a little less than 5"x3"

Rocknchairhippie's answer is correct: the door opening is 9x11 inches. But our cage has two doors of this size: one at the upper level and one at the lower. If you look closely at the photo, you can see both doors. It's a great cage.
