Quick Scoop: Excel 2010 Row Limit

Q: “What is the maximum limit of rows in MS Excel 2010?”
A: 1,048,576 rows per worksheet.

Key facts

  • Excel 2010 worksheet size: 1,048,576 rows × 16,384 columns (A to XFD).
  • This “about one million rows” limit is the same for Excel 2007, 2010, 2013, 2016, 2019, and Microsoft 365.
  • Older Excel versions (like Excel 2003) only had 65,536 rows , which is why some users still see that number in old .xls files.

Why that exact number?

  • 1,048,576 is 2202^{20}220 (a power of two), which fits neatly into Excel’s internal binary design.
  • Using a power-of-two limit makes it efficient for Excel to handle indexing and memory.

A quick way to “see” the limit: press Ctrl + ↓ in an empty column and you’ll jump down to row 1048576.
