I have found there to be namy variations of size of the 44 pin QFP's and TQFP's. I ensure I have the proper footprint I will often print the artwork out on my HP Laser printer and then put the IC itself on the printout and look how the feet fit to the pads.

Maybe you already did this? :-)

Yes of course I did! ;-)

My PCB layout software (Layo1) did not have any QFP footprints, so I drew one based on the drawing in the datasheet. The chip fits nicely on the printout...

Best regards,
