Engineered wood (MDF), not solid wood, with a smooth, even finish.

Clear plastic, not glass: far lighter, and much less likely to shatter.
Ready to hang
Sawtooth hangers come attached to the back. Add a nail or hook and it is up in minutes.
Easy-open backing

Customers keep coming back for the wall
Hang it straight in minutes

-
01
Unbox the frame
Lift the frame out. If the front has a clear protective film, peel it off.
-
02
Pick your spot
Choose your height — eye level is a safe default. Hanging a set? Lay the pieces on the floor and arrange them first.
-
03
Mark the wall
Hold the frame where you want it, pencil a light mark, then measure down to where the hanger will sit.
-
04
Set the hook
Drive a nail or wall hook at your mark. The hangers are already attached to the back of the frame; the nail or hook is yours to supply.
-
05
Hang and level
Set the frame on the hook and nudge it until it sits level. A small level, or the level app on your phone, makes it quick.
HANGERS PRE-FITTED · NAIL OR HOOK NOT INCLUDED
Answers before you order
Will my print fit — and what does “matted to” mean?
Every frame is built to a standard print size — 4×6, 5×7, 8×10, 11×14, 16×20 and up — and the size in the name is the frame size, not the outer edge. “Matted to 8×10” means the mat window is cut for an 8×10 print inside an 11×14 frame; lift the mat out and the same frame takes an 11×14 print edge to edge.
Three numbers sit under the size picker on this page and follow whichever size you choose: the print size it displays, the true mat opening (about ¼ inch smaller than the print, so no edge shows) and the real outer size of the frame. Measure your print and match it to the print size — or to the frame size if you want it unmatted. The full pairing table is in the Size Guide.
Right size, guaranteed. If it still isn’t the size you needed, email help@americanflat.com within 30 days of delivery with your order number and the size you want. We send a prepaid return label and ship the new size at no extra cost — the original just needs to be unused and in its packaging.
Is the glazing real glass or acrylic?
It depends on the frame and the size. Many styles use 2.0 mm shatter-resistant glass, larger frames and poster frames mostly use plexiglass, and a few styles use standard glass. The glazing for each size is listed in the product details above.
What are your shipping and return policies?
Free standard shipping on orders $99+ under 100 lb within the contiguous United States.

Arrives damaged? We replace it — no return needed. See the next question.
What if it arrives damaged?
Arrives perfect, or we replace it — no return needed. Email help@americanflat.com within 14 days of delivery with your order number, a photo of the damage and a photo of the box it shipped in. We ship a replacement and you keep the damaged one — nothing to pack up or send back.
Is custom sizing available?
We focus on standard sizes rather than custom cuts — but the range is wide, from 4×6 up to 24×36 and larger, with matted options that fit most common prints. There's almost always a stock size for your photo.
