Graphics Card Widths Explained

I’m going after a venture and need to find the thing of the width of an average double slot graphics card (unfortunately, I don’t have one right here with me). 

I expect a regular backplate is of height 107mm, and a low profile is 64.41mm at max. When measured, the width showed 175.26mm, and triple-half is anywhere between 174 mm to 310 mm. Will the slot fit in the compartment?
