Have measured my bra size as 29C but that size doesn't exist. What size should I try instead?

I've measured my bra size and I'm 29 around my rib cage and 32 around the bust, which makes me 29C. However that doesn't exist. So should I go up a back size and try 30C? Or because I'm going up half a band size, should I drop down a cup size to 30B? Or do I go down to a 28 back size like a 12 yo? It's all very confusing.

And where can I get bras with a small back size?

30B or C, I'd say.

Try a 28D, a 28C and a 30C. Trial and error really, especially on the cup size which will differ hugely between styles. The back shouldn't differ quite so much although some brands are tighter than others. I mesaure 30.5 and definitely prefer a 30 to a 32.

Bravissimo, John Lewis, Debenhams and HoF all stock 28 and 30 backs.

Thanks, I'll give all those sizes a try.
