Spinnerbait frames are made in standard sizes and will be listed as R3, TW4, etc. R is for R bend and TW is twisted loop which are the most popular. The number behind it corresponds to a specific head and arm length. For example, a standard War Eagle spinnerbait is an R3 while the Screaming Eagle is a R2. Bigger the number the bigger the frame size and 95% of bass baits use a 2-4 frame.
Wire type and diameter are the next thing to tackle once you figure out frame size.
I would need more information on what you are doing to help you further.
