It's really hard to say because it depends on the efficiency of the furnace, your home's layout, the building materials used, and much more. The method used by most contractors is called a Manual J Load Calculation, which incorporates all of the variables to arrive at the right size furnace for a home as measured by BTUs and other considerations.

Therefore, your best bet is to get an HVAC technician to come in and properly calculate the size furnace you need. You can find one here: http://www.furnacecompare.com/choosing_a_contractor.html.
If you want an estimate it you can look on the furnace that you have now. However, improvements to the technology mean that furnaces run far more efficiently than in the past so you may not need the same size as measured by BTUs.
There are also websites that can help you calculate this, but these will be only a best guess.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl
