I misplaced my iPad how can I find it?

Expanding upon prior contributions...

Here is Apple’s advice for lost or stolen devices:

If your iPhone, iPad or iPod touch is lost or stolen – Apple Support

Use the Find My app to locate a lost or stolen device – Apple Support

If the Find My iPad feature was enabled prior to it being “misplaced”, then if active, you would stand a good chance of locating it. 

However, if the feature was not activated prior to being misplaced - or the iPad has been inactive for more than 24 hours, the last known location will not be available - and the opportunity to use technical means to recover the iPad have been lost.

If you cannot locate it using the information found in the link that Idris provided, then the only option you have is to actually look for it. There is no other way to locate it except what is shown in that link, and looking for it the old fashioned way.

I agree.....start looking. One thing you can do is turn the volume down on the device you are currently using, send yourself a few text messages and listen to hear for the sound of the messages coming through on the missing iPad. If it's in your house or car, you may hear it. Backtrack to wherever you were and keep listening. Of course the device would need to be on.
