..... And determining the "size" of an MSI can be a royal pain. If you mean
"when it's about to be installed" then it will be accurate only after the
costing is complete because features have been picked and Windows has worked
out which files are actually going to be installed. If you just want a
generic approximate size to show, then write a dumb build tool that adds up
all the sizes in the file table and stores the result in the Property table
were it can be queried.

Subject: Re: [WiX-users] determining the install size of an existing msi

MsiPackage element is used by Bundles. That data is provided in the
BootstrapperApplicationData.xml file provided to BootstrapperApplications
running in Burn. Not clear if you are writing a custom BA or if you have a
custom bootstrapper engine. For the latter, you'll have to write all the
infrastructure yourself.
