Is there a calculator for cutting pieces ?

I'm not sure what it would be called.. basically I'd love a calculator that gave me a sliding scale of how many / size of pieces I could get out of various pan sizes. ie. 13in x 9in pan can be divided up into the falling ways: 20 "x in by x in" inch pieces, 25 "x in by x in" pieces.

Of course, there might be some answers that leave some wastage if you want just whole numbers or rounded to nearest half inch. etc

Anyone heard of something like this ? When I googled it, my closest results were from patchwork quilters and their calculators.

Many cakes come with a diagram like that on the box, but for the specific sheetcake.

If you really want the math in a 13* 9 do the math grab a piece of paper and draw it out. Then you will really KNOW it.

I just start in the middle with my knife haha. 1 cut = 2 pieces and so on :)

@ChicagoTerry  ,

My post doesn't have anything to do with you. It's the link. I have to confess, I have not used cup measurements since Home Economics class in 1969.

The first thing I saw on that page was a 8" cake pan using 4 cups of batter. I'm thinking that cake might take 5 hours to bake. Maybe 1/2 hour to bake, and 4 1/2 hrs. to clean the bottom of the oven. I can be completely wrong.


  Something like this?

For information on cutting party cakes, please see Wilton's Party Cake Cutting Guide.

Move in two inches from the tier's outer edge; cut a circle and then slice 1 in. pieces within the circle. Now move in another 2 in., cut another circle,

Nope.. but if I get around to programming what I need I'll post it here and see if it's useful to anyone else.

Ah..thanks Pannini. Someone posted one of these tables (in cups) here on CT a couple of years ago, which I printed out because for me, a home cook in the US, cups are fine. I don't know where it came from but it is not this one, which I found linked to in a thread which is obviously not the thread where I printed my copy from. I can't find that other thread.

I have collected one or two charts over the years.

Some are from the internet some torn from the Wilton hobby baking booklets. I would print the ones that looked pretty as well as functional and planned to make my own "super chart".

Someday never came and I threw out most when I retired...the rest went into tubs with most of the cookbooks.

For some reason the fisherman put all of those tubs at the back and under everything else (rented locker) and are not worth the work it would take to dig them out.

Every six months or so I come across some poor soul wanting bakery charts and the only place I can think to send them is (now) Pinterest.

LOTS of charts on Pinterest!
