Ok, that's a little different
There's a few "measuring sticks" that can be used for comparison. The first is the Full Moon, it's angular size is 1/2°, or 30min of arc (30'). The Andromeda Galaxy is roughly 3° long by 1° wide. So with the Moon as a yard stick, it is 6 full moon's long by 2 full moon's wide.
I copied the following from the website "one minute astronomer". The page also contains some diagrams for the following.

"* Stretch your thumb and little finger as far from each other as you can. The span from tip to tip is about 25 degrees.
**Do the same with your index finger and little finger. The span is 15 degrees.
* Clench your fist at arms length, and hold it with the back of your hand facing you. The width is 10 degrees.
* Hold your three middle fingers together; they span about 5 degrees.
* The width of your little finger at arm’s length is 1 degree."
These are better than using coins as a measure.
I hope this helps some more
