Typical sizes run from small 8" x 8" tin signs up to roughly 19" x 19" metal panels. Common options shown in listings include 8" x 8" and about 19" x 19".
These items are made of metal. Some listings specify lightweight 16-gauge (≈2 mm) steel and note a textured static powder-coat finish for surface protection.
Mounting options shown include a backside hanger for easy hanging and pre-drilled holes in all four corners for nailing or hooking; some products also include hangers with the item. Exact hardware varies by listing.
Listings show horizontal displays and items that support both horizontal and vertical mounting. Whether both orientations are supported depends on the specific product.
Some metal panels are designed to stand roughly 0.6" (1.5 cm) off the wall, creating a subtle floating look that produces a drop shadow and a 3D effect.
Listings note smooth rolled edges and rounded corners (or rolled edges with rounded corners), which are described as making the signs safer and more comfortable to handle.
At least one listing specifies lightweight 16-gauge steel (about 2 mm) as the panel thickness.
