30" or 45" shoot through umbrella?

I own a Qbox 24" which works great but I want a liter setup for traveling. Will a 30" white umbrella enough for half body shot? Do I need a 45" in order to do full body shot?

45" will be ok for full body, but I would get the 60"

Don't you guys think the 60" is too big for traveling? The OP wanted a lighter setup thats easy for transport while traveling.

I think the 30" is too small. Perhaps the 45" is just right for travel purposes.

What is the problem with folding Qbox24"? It is pretty small IMHO.

Can't fit into my Manfrotto LBAG90 and I want to add more lightstands in the future

I personally wouldnt go with anything smaller that 45". Being umbrellas they fold up very small. 45" and 60" arent too much of a size difference when closed IMO.

Right.....and if you're wanting to do full body shots you gotta bring the right tool for the job.

The only exception being the Wescott double fold, but I don't think they come any larger than 43".
