If your garage door spring snapped like mines and wonder if you can fix it yourself then you definitely can but need to be very cautious when winding up the spring because it can be extremely dangerous. I did this myself but I would recommend to ask a friend to help out.
Below is the website I found very helpful when I did this replacement. Scroll at the bottom of the page and it will ask you a few sizing questions and like I said in the video if you can't seem to figure out the exact size of the wire gauge (wire size) because it's so difficult to measure then go with a tad thicker wire just to be sure, unless you have a caliper which shows it perfectly. The diameter (ID) is easy to measure, usually they're 2" inches by standard and then lastly it's the total length which is also easy to measure.
