Why I Consider This Frame Size

What I Check Before Buying
When I buy a frame, I always check a few important things:
- Exact size: I make sure the frame matches 30 by 40 cm or the print size I already have.

What I Avoid
I try to avoid frames that feel flimsy, have weak backing, or do not hold the print securely. I also stay away from frames with poor finishing because they can make even a beautiful photo look less attractive.
