I just found out that Ikea's largest picture frames in stock now is only up to 40x50cm, which is usually good for A3 size. For larger prints, they no longer have any stocks.

These larger sizes are no longer listed on the Singapore and also the US websites. I spoke to Ikea this morning and was told that they have zero stocks of the larger frames, and unsure when new stocks will arrive as the stock-out could be due to a change in suppliers.

Besides custom framing which is expensive, where else can I buy standard frames for A2 size prints? Any advice appreciated.
