Guitar strap installation methods?

[Mujician]

I think the wide bit at the front and thin at the back looks really odd. I have made two adjustable straps but have never been sure of the measurements. I just winged it each time. Is there a sure fire way of measuring up to make a guitar strap in this manner?

I'm not sure if there can be any sure fire way. The guitars can be so different and the way a user wears them as well the only safe way would be to measure in person....somewhat. If you can get a previously used one from them can help. Other than that they would have to give you the measurements between the holes and as I have done put one either side in case of stretch or extra width problems etc. As the Chief has kindly shown above, I think would cover just about any possible size variations.

Hiya everyone. Hope all is well. I'm in the thinking out stage of making guitar and rifle straps from paracord. My question is does anyone know where you can buy the adjustable strap portion only. I've searched and searched but no luck. I'm also in the art stage of two leather straps for the same purpose. I'm a disabled mechanic, kinda new to being not able to be active anymore,, so I found that Paracord and leather allow me to be somewhat creative.  Just not sure what parts are called .  If anyone can point me in the right direction,why id be mighty appreciative.  Thanks to ask all in advance, God bless ya all. My name is Mark.  Thanks allowing me your time.
