Row Height/ Font Size

[StevePM]

I have inherited a workbook in which all of the sheets have their row heights set to 20.25 (27 pixels) and font/size Trebuchet MS 12. However, if I create a new sheet in the same workbook, these settings make everything look larger and I have to set the row heights to 13.5 (18 pixels) with a font/size of Trebuchet MS 8 to get it to look like the other sheets. If I copy one of the original sheets using move/copy, the original settings copy too but not if I copy/paste into the new sheet.

Does anyone know why this is happening? I don't know which version of Excel was used to create the original workbook, but I'm using 2003.

Thanks.
