SportRx Frame Width™ 
142mm
142mmSportRx Frame Width™ (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.

SportRx Frame Width™ Chart
*All Sizes in MillimetersDETERMINING YOUR SFW
Use Eyeglasses and Not Sunglasses
Using flatter eyeglasses makes for a more accurate measurement. It takes a bit more finesse with wrapped sunglasses to get an accurate SFW measurement.
Have more than one pair?It never hurts to have more than one 'frame' of reference! If you have more than one pair that you love, you can measure multiple pairs and get an average.
Make sure the glasses fit!
Since we're using your glasses as a template for ideal fit, make sure they're a pair that are comfortable: not too wide, not too narrow. A quick glance in the mirror will show if the frames spread too far past the edges of your face or seem to 'pinch' it.
How/What do I measure?Measure with the temples opened out fully. Aim for right behind the hinge and measure from the inside of the frame material of one side to the inside of the other side.
If you require a moderate to high prescription, this Rudy Project Rx dock provides the tailored sight-enhancements you need without reducing the original Deltabeat benefits. This optical dock is flatted to a six-base wrap for your Rx needs and easily snaps into the frames. The thickened edges of these lenses also provide protection that’s similar to an eight-base wrap — so your game is undisturbed by peripheral UV rays, dirt, dust, and debris. If you or your loved ones don’t have Rx needs, the original non-prescription Deltabeat is also available.
