Dimension A Frame Buggy Picture Frame Dimension Help?

Picture frame dimension help? - dimension a frame buggy

Hello. I have a picture frame with a picture inside but the glass broke, I'm looking for a photo with the same dimensions as the glass picture frames that I measured. Dimensions of the picture frame is: x 4.11 6.10 cm and 12 x 17 cm.
I'm looking at this size, but can not find. To save the view of the dollar, but the size is closer to
5 x 7 + 13 x 18 () would be too great
or
5 x 7 + 12.7 x 17.8 (which was too large)
Where can I find an accurate measure of my picture frames?

Thank you! (sorry if this sounds confusing, it is not really)
