Buying Guide: Key Purchase Considerations
- Matting and display options: If you plan to use mats, verify the actual opening size and how much the overall frame reduces the display area when matting. Some frames are designed to accommodate both 18×24 and 16×20 with mats, offering flexibility for future changes.
- Material and finish: Frames in black woodgrain, MDF, PVC, or engineered wood affect both aesthetics and durability. Plexiglass provides shatter resistance and a clear view, while glass may be clearer but heavier and more prone to breakage.
- Mounting orientation: Look for frames that support both vertical and horizontal hanging. Pre-installed hardware and sawtooth hangers simplify installation and help with alignment on walls.
- Protection and longevity: A secure back, proper sealing, and a high-quality cover help protect photos from dust and moisture. Consider UV protection if the frame will be exposed to direct sunlight.
- Size compatibility: For an 18×24 display, ensure the frame either matches exactly or can comfortably display the image with a mat. If you anticipate future art changes, choose a frame with flexible size options.
- Budget and aesthetics: Choose a frame style that complements your interior—modern, traditional, or minimalist—while considering whether you prefer a slim border or a bold, wide molding.
