I can only say that it will fit a perfectly round steering wheel. If it is an odd shape it will not fit.

Ok, I DO NOT own one of these, but while looking for the same answer, I think Sarah has the circumference, not the diameter. Jose might have a more accurate diameter. I only say this because 4 inches seems really big, and since circumference = pi * diameter, if we do 3.14*1.33(Jose's answer), we get approximately 4 as the circumference. Just my suspicion, again I do not own one. My guess would be that Jose is accurate and 1.33" is the diameter. Just a heads up and something to think about for other curious buyers like myself.

I am sorry I am unable to answer your question. I am not even sure how to measure circumference for you...

I just received one today 10/4/14 and it is 15 inches! Not very usable. I am returning it.

If the circumference is 8 inches the diameter is 2.546 inches. The only answer that makes any sense is that 8 is the diameter.

Approximately 17 1/4". Just FYI, circumference is the diameter of a circle x 3.14159 (which is pi). I had a really good geometry teacher! Also, some of the other answers are a little different but my light is 5 1/2" in diameter which is where I came up with this answer.

No. The dimensions are specified in the description. Find another size by same brand

mine is 29.5 inches diameter and about 82 inches in circumference. It's easier to put together than some reviewers have said.

Sure. I got 2 extra large, diameter approx 3 1/2 and 4 large, 2 1/2. Work really well. Thanks for asking.

I measured the circumference, and took a guess, but it was too small so go one size up from that,. my advise

Hi. I measured the circumference as 1 3/4" or 44 mm. near as I can figure this makes a diameter of 14.0127 millimeters. I hope this helps.

May be a bit too small, according to the dimensions. Go with the 1500 size to be safe.

you have to measure the diameter as previously commented rather than rely on the size from the charts, then go with the size that falls in the range

2 inches in diameter (measured) = 6.2857 inches in circumference (calculated)

Pretty close to what I got...I came up with 18 inches high, but it's hard to measure. 14 3/4 to 15 is a good diameter.
