how to measure v band

[junkyarddsm]

I know this is a dumb question but I really want to know that i am getting it right. How do you properly measure a v-band flange? I used my caliber to measure the inside and got 2.5 and an out side of 3. Just to be clear you do not measure around the pipe right? I know it sounds dumb but my new setup uses a v-band and I need to get it right. The turbo is a holset hx30w internal wg.

I use siliconeintakes website all the time, The have all the dims of the v-bands they carry. But most holset turbos do not come with standard size v bands. more likely then not you will either have to machine a new vband down or weld a new vband onto the turbo side of things.
