The size of a spreasheet is as large or small as you need in either Lotus or Microsoft Excel. I have an antena design formula which takes up over 900 "boxes". It is quite complex! A difficulty may arise when printing, especially a small one.
Click file, then page preview & page setup, last choose fit all to page in the lower left of the A/Z in the properties menu. The larger the spreadsheet the smaller the text will print.
I hipe this answers your question. Good Luck and Thank You.
