If you want just the SRD-05VDC-SL-C relay on its own:  If you want the complete module including the connectors and LEDs etc. then you need to understand that: 1. this module is not designed to be mounted directly onto a PCB: 2. the modules are poorly documented so unless you can find a good quality datasheet for it or you have already obtained a module to measure yourself, you cannot make an accurately dimensioned PCB footprint for it; 3. it has no mounting holes and therefore has no obvious way of locating it on a PCB;  4. the underside of this PCB will have through hole component pins sticking through it so it cannot be mounted directly over a PCB area with other components on it.

There's some dimensional info for a module like yours in the Features section of: [https://www\.ebay\.co\.uk/itm/5V\-Relay\-Module\-SRD\-05VDC\-SL\-C\-250V\-125V\-AC\-30V\-28V\-DC\-Arduino\-Flux\-Workshop/111607485798?\_trkparms=aid=555018&algo=PL\.SIM&ao=1&asc=20140122125356&meid=dcf5b7615a51479fa7429a45c017c9ac&pid=100005&rk=2&rkt=8&mehot=ag&sd=113148452543&itm=111607485798&\_trksid=p2047675\.c100005\.m1851](https://www.ebay.co.uk/itm/5V-Relay-Module-SRD-05VDC-SL-C-250V-125V-AC-30V-28V-DC-Arduino-Flux-Workshop/111607485798?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20140122125356%26meid%3Ddcf5b7615a51479fa7429a45c017c9ac%26pid%3D100005%26rk%3D2%26rkt%3D8%26mehot%3Dag%26sd%3D113148452543%26itm%3D111607485798&_trksid=p2047675.c100005.m1851) but it is practically useless because it does not define the pin positions with respect to the board edges.

This post gives some advice on how to drive the relay as a standalone component: [https://easyeda\.com/forum/topic/How\_to\_drive\_5V\_relay\_with\_SMD\_componant\_\-L9lV64ECc](https://easyeda.com/forum/topic/How_to_drive_5V_relay_with_SMD_componant_-L9lV64ECc)
