We've considered durability, ease of use, and affordability when making our selections, but not worried too much about "inaccurate" pet sizing. Most companies that make pet doors encourage you to measure your animal, anyway, and not just rely on weight ranges or size designations like "small" or "large." As with, for instance, clothing sizes, these can vary quite a bit, but a measuring tape, wielded properly, won't lie.
As for top choices, the PetSafe Freedom is still a reliable option, as is the PetSafe 2-Piece. The Freedom model is a single-piece unit, whereas the 2-Piece, as you can guess from the name, breaks down into two parts. This makes it easier to store than the former, but it doesn't come in as many size options as the Freedom. Options from Ideal remain popular, as well, including the Ideal Pet Products VIP and the Ideal Pet Products Fast Fit.
If you're in the market for something a bit fancier, take a look at the Thermo Panel 2e SureFlap, which gives you the well-liked SureFlap pet door in a frame that's designed for sliding glass doors. You can set it to recognize up to 32 pets, but they must be on the small side, as this model doesn't come in a large version.
