That's the only size it comes in these days. Years ago you could get it in all the sizes, but now all the crystal is imported from Europe and to get it shipped here they'll only cut it in 3.5", an auto manufacture actually has to cut it to ship t here. They can cut it in different sizes, but you'd be paying for special cut at a high price and limited supply. All the manufactures agreed to all use the 3.5" to save on cost and still have a good supply. The minimum cut was 50,000 at about $10. a slice. It's a lot easier and cheaper just to make a 3.5" call.
