roomephantCan I see a floor lamp next to my sofa before buying?
Yes, and floor lamps are worth previewing precisely because their product photos are so misleading. A lamp shot alone on white gives you no idea whether it will tower over the sofa or disappear behind it.
Height is the number that decides it. A reading lamp next to a sofa usually wants the bottom of the shade somewhere near eye level when seated, which lands most of them between 140 and 160 cm. Listings publish this.
Shade width is the second one and it is easy to miss. A wide drum shade next to a sofa arm can crowd the seat in a way the product picture never suggests.
Thin metal stems are the hardest thing for an image model to draw, especially a pale lamp against a pale wall. If the result looks off, try the spot again with more of the wall and floor in frame.
A lamp is also the item where getting the size wrong is cheapest to fix, which makes it a good first thing to try if you are testing what a preview can do.
