You can calculate the frame size of your bike a bit more accurately as follows:

Always take your inside leg measurement without your shoes on. You measure your inside leg by standing with your legs about 15 cm apart and measuring the distance from the floor to crotch height. If you multiply this measurement (in cm) by 0.68, it will give you the corresponding frame size.
Is the frame size between two sizes? If so, use the following rule: if the bike is for sports use, then choose the smaller of the two sizes. Is it a touring bike? If so, go for the larger frame size.
Do you have a bike with a suspension seatpost? If so, then subtract 4 cm from your frame size.

You can of course measure the frame size of your present bike. Do so by measuring the end of the seat tube to the centreline of the bottom bracket. Allow for the 4-centimetre correction quoted above with a suspension seatpost.
