Put the real size next to something they already own
People do not fail to buy because they cannot read centimeters. They fail because they cannot imagine the object on their table. A listing that says 18 cm still asks them to do math in a kitchen they cannot see.
I started placing one familiar thing in the frame — a spoon, a paperback, a house key. Not a pile of props. One. The bowl became a breakfast size. The frame became a hallway size. Questions about scale dropped almost overnight.
If the piece is larger than it looks, say so in the first sentence under the photos, then prove it in the image. Numbers support the picture. They should not replace it.
On Doshe, the listings that feel easy to live with are the ones that already look lived with. Give them a size they recognize, not a measurement they have to trust.
