The reason it shows two diff sizes, is because for a smaller tank you would just trim to fit

Disregard my first answer, this is not the product I have, it's smaller than the one I purchased.

I purchased two different ones from the different listings thinking they were different sizes but they weren't.

I only saw "one size" when I bought my chairs. I'm not sure what the other one is. When I look back at what you are seeing it does seem confusing. This might be a posting issue as they both seem to be the same.

Hi, It appears smaller but the actual size is as stated. I purchased it because it looked smaller than stated and I was SO wrong. It didn't fit 13" space, it was too wide actually 15". I wanted to return it but you must pay for restocking fee for selecting the wrong size. After paying $100+ for it I was informed that I would receive a credit only $70. So kept it and used it for something else, somewhere else! I must say it's sturdy and of good quality. The latch gave me a hard time assembling it as it wouldn't quite line up. Good luck!

I'm sorry, we used it a year ago. It worked very well, and actually it has been used twice since.I don't have the actual sizes.

It's a regular size one. I ordered mine about 4 months ago and have no complaints!

I'm not sure, it may be the actual heigth and length, I remember looking at another model and it was the same length but too short

I don't know. The one I got was supposed to be a large & it was a small so I returned it & never got it replaced

I believe this one is the larger of the two measurements. I was taken aback by how large it was when it arrived. but I actually like it and am glad it is so big.

I'm not sure why it's presented as both sizes. I ordered it and received the 13x19, which is the size I wanted. AC

We only bought one so I don't know about different sizes. However it looked smaller than the picture.

I did the same thing. Just take a ruler and measure. Then go check the different available sizes (not only the one of this item). usually you can then tell if you are closer to that one or another size.

Thank you for your answer. We are looking for a large pad and just wanted to be sure before ordering, but was concerned when I saw 2 different measurements. Thanks again.

They actually sell both sizes on Amazon since I bought one of each. Just double check the description before you order because sometimes the photo doesn't match.

Maybe- I am not certain of the actual size as I shipped it directly to my grandson. Sorry I can't be of more help here.Bill

It's 2 1/4". I don't know why people just guess when they don't know the answers. I'm returning the one I purchased that was too big.
