Altitude of an airplane in flight

How do I figure out the altitude of an airplane in flight?


I live one street away from a regional airport and small jets take off over my house every day. I’ve always been a little nervous about this as most small jet crashes are on takeoff, not on landing. The airport has altitude restrictions on takeoff, but I’m wondering if the pilots are adhering to those policies as they seem a lot lower to me. I was trying to figure out how I can tell how high they are when they pass over my house but can’t find anything on the web or on here to help me figure it out. Can anyone help me with this?
