Please help
I want to make a rectangle quilt using 12" blocks set on point, with finished size aprox. 60 X 70. How many blocks will I need? I have made several on point quilts, but they were always square. Any help will be very appreciated.

moda fabrics has a page of charts
click on the fourth chart down here:

hope this helps.
here's another chart that has all the math, but if you scroll all the way to the bottom of the page, there is a cheat sheet of common sizes

A 12" square on diagonal is essentially 17". When we do rough calculations you can use 1.5 times the finished size but that's a bit large -- it's how I figure the setting triangles though to make sure they are big enough, a common error is taking the size of block and cutting in half but that's not enough for the seam allowance.
So 4 blocks across with no sashing and no borders would be 68" (4*17). I'd probably go 3 across and 4 down -- but remember when you set on point you have alternating length rows plus the setting triangles. So, if I'm counting it right that would be 3 rows of 4 (12) plus 2 rows of 3 (6) for a total of 18 blocks and add the setting triangles to that.
I've included a layout I drew up earlier this year and now is in my handy notebook, sometimes it helps to actually count.
Also a couple handy sites,
All sorts of calculators and help here:

Simple diagonal site for when you don't want to just do it on a calculator...

You can have the side measurement or use it to figure how to square the diagonal, depends on what you know.

I wanted to put in another site I use a lot to help me figure out quilt stuff,

No affiliation, just so much good stuff and updated periodically so if you haven't seen it lately check it out again. I've been thinking a lot about 3D and other illusions in fabric lately and just might be able to put this perspective grid to use in the near future...

When I was younger, I could do a lot more visualization and mental math. Nowadays I rely on calculators, websites, and do a lot of design on Electric Quilt or in my notebook, and I've been cheap and haven't bought an upgrade to my Electric Quilt and can't put it on my current system, so it's been notebook time.
I find that while I enjoy designing on computer, in some ways I'm more aware of construction issues when I'm working with paper. And sometimes, it just helps to count on my fingers or on my grids and I'm ok with that

What block did you have in mind?
Were you planning to use sashing between the blocks?
Were you planning on adding borders?
Are the blocks you have in mind easy to downsize?
Some of the 3 x 3 grid blocks are easy to down size to 10.5 or 9 inch square blocks.
Some of the 4 x 4 grid blocks can be downsized to 10 inch or 8 inch blocks fairly easily.
