Confusion in selecting relay while designing pcb in eagle
You're going to need to create your own footprint in Eagle.  You can find the device measurements in the datasheets for one of those parts.  If you have access to a printer you can print off a 1:1 representation of your footprint to make sure the part will actually fit in the footprint you design.  That will save you from having to wait several weeks for your boards to show up only to find out that your parts won't fit.
