It's doubtful there is a standard. They come in a variety of sizes, shapes and materials. See, for instance, the ref. below.

call basspro or cabelas and they'll send you one.  A better idea would be to pick up a current equipment guide and find out the scoop behind the products.

I haven't done one of these in quite a while. \n\nWhat would you differential element be?  How about r*(dtheta)*dr?\n\nthat sort of a ds*dr   where ds depends on the radius.  Try it! \n\nNote that without the sin theta you'd get the int rdthetadr with r 0 to R and theta 0 to 2pi  You'd get the correct area of a circle.\n\nTry the intergral, see if it makes sense.  Then sketch the figure and estimate it's area to compare.  My confidence is increasing as I write this.
