Quick curtain question

[Babyjunglesafari]

I’m about to order curtains for toddlers bedroom. It’s the small 8”x9” bedroom.

Window is 114cm drop.

Should I order curtains with a 137cm drop, or a 183cm drop?

I guess it’s personal preference but not sure which would look best.

Can you pin up a duvet cover or other curtains to judge the effect?
I think in small room curtains are better at sill length as you may want to put furniture or have a radiator under the window. So 137 will be OK.
