Issue in image padding

[RespectKnowledge]

Thanks for published great work I really appreciate your efforts. I have very basic question related to image and label padding function. My image size is 247365 and it's very throughout the complete dataset. When I use zero padding let's say padd_size= (24,96,96). The zeeopadding function produced different size let say 269797.
Is there any suggestion, how to handle this issue? Once again thanks
