Help me pick a frame size

I’m looking at picking up a road frame. I ride a 54cm Felt DA and fit great in a TT position. How do I best determine what size road frame I should get?

Can someone refer me to an article or offer some advice? I have measurements of my body from a Retul fitting. Would that help?

Thanks!

Might be worth looking up the stack and reach database on this site. This will give you those figures for your felt da and should he,p when choosing another ( not sure if stack and reach is just used for tri bikes though)
