Obviously all theoretical. Unless…
The following assumes that they’re tiny humanoids with wings and no magic spells/powers.
What would you say the size range is for our tiny winged beings? I often imagine incredibly small, like AA battery size. Then my brain makes like a runaway train, thinking about things like logistics and plausibility (I know they’re fictional magic beings but that’s the runaway train part).
Once I get into that mode, I start imagining them bigger, to an extent. As big as a futbol, usually. All the various children’s stories have them anywhere from palm-sized to as small as bugs.
I guess for imagery sake, imagine you had a roommate that was one, so you have to take their size into account for things like cooking and cleaning. What chores would be exclusive to each person based on size? Would they be able to lift/carry human-size objects?
They’d probably be covered in fur to reduce chances of freezing to death, something that small with that much surface area is going to lose heat at an extreme rate, and if they’re humanoid they need to metabolize to maintain body temperature.
