Since Excel 2007 (Windows) and Excel 2008 (Mac), the number of rows in a .xlsx, .xlsm or .xlsb worksheet is fixed at 1,048,576. That is 2^20. Excel only stores the data and formatting actually used, so there is no penalty for having such a large number of rows in every worksheet. The file format isn't being changed for Excel 2016, so the same maximum number of rows still applies.
