Need help with sq ft of steam radiators

Gmc310

Ordered a boiler and not sure if it's big enough. I have a 21 inch tall 12 section cast iron radiator. 2- 36" x6" convectors a 46"x6" convector and a 19" x6" convector. Totaling five radiators for a 900sq. Ft. Cape. The measurements on the convectors are without the sheet metal enclosures. I also have 68 linear ft. Of piping to get to the radiators. I did a heat los. Calc and came up with 31k btus of loss and that's what they used to figure on a boiler size along with the other info I listed. We never talked about sq footage of the rads and it has me worried. Thanks for any help anyone can offer. Gary from Boston.
