Torsion Springs Measurements

How do I measure double springs for a 16 feet wide x 7 feet height garage door? It is uninsulated. I don't want to use the current double springs as measurements because who ever installed them, they are uneven (not exact length) springs. They have been working for 15 years but it is time to change them out.

Also, what are the best type to buy for HIGH CYCLE? I read it is oil tempered right?

OIL-TEMPERED SPRINGS (Last the longest)
POWDER-COATED SPRINGS
GALVANIZED SPRINGS

I believe my current ones are steel looks like springs.

I am attempting to do this job by myself, understanding the danger behind it.

many manufactures use different length/size spring to make the door balance properly (usually when the glass is in the top section) How does your door balance by hand with the opener disconnected? I would need to know the actual door weight, drum size and does the door have any highlift? Or the old spring sizes (they may be on a label somewhere on the door)

Aren't torsion springs color coded like standards springs are ?

Sometimes an end of the wire is painted indicating a wire size but can be hard to see, worn off or not there if it was replaced once. Some companies put the wire size on a track label or a spring tag.
