Studio size?

I am considering lining part of my shed, the area I have available is 3m x 6m (9'x18')
I'm concerned that I will find it a bit small, what are your thoughts?

Depends on what your subjects will be and what you wand to acieve.

Ceiling height is another concern.

For portraiture, 1 to a few people.
Ceiling height is about 8'

At that width, you won't have much space to work once lights are in place. I would go any narrower than 12'.

This I agree with. There are plenty of variables to take into considerations and this is one where size isn't all that matters.

When I first started in photography I worked for a photographer that had several studios throughout the local region. I worked at his main studio where he had three studio rooms where the smallest was probably about the size you had indicated and the largest was quite big in that we could pose full wedding parties in it and not feel cramped. We were using medium format cameras with a wide selection of lenses available to us.

There have been many previous threads that covered the same subject matter that might provide an answer for you as well.

You should be fine. I shoot in a 9 ft X 11 ft long studio with a door in one end. Ceiling is 8ft.
Would I like more room, hell ya, but it is what it is.
