Technical term for the size of each hole in IDC connector

[wajahat]

Hi everyone , i want to know what is the term used to define the size of each hole in IDC header.
I have attached 40 pin Idc connector picture.
Is there any 80 pin IDC connector.
Any response in this regard would be helpful.
Thanks

hole size in PCB for IDC is 0.9 but for 2 layer metalized board 1mm is better.
i used 50pin IDC,it is too big and i looking for smarter solution,such Standard SCSI cables. but i can't imagine 80pin IDC (more than 40 * 0.1 inch long).
