The total of the two has nothing to do with it, but a picture - with you on it, in riding position with the cranks parallel to the ground - would be required to make a judgement with any accuracy at all.

When I fit a new bike to myself, I try to get the following measurements as close as possible to those of old bike:
1) Length from the bottom bracket to the top of the seat.
2) The fore/aft location of the saddle, as compared to KOPS
3) Length from the saddle's "sweet spot" to the handlebar.
4) Saddle to bar drop (optional)

Of course, they won't ever be exactly the same, and the most important part is that the bike is comfortable.
