Multiplication Chart (1 to 20)

A full multiplication chart from 1 to 20 in one reference grid, with the patterns that make the larger numbers easier to learn.

A 20×20 chart extends the standard times table to cover products up to 400. It is the reference chart used in middle school and above, where questions start involving two-digit factors, area problems and algebra. The diagonal still carries the perfect squares (16, 25, 36 … 400), and the grid remains symmetric, so the two-digit half follows exactly the same rules as the tables learned earlier.

How to read this table

Find the first number down the left-hand column and the second number along the top row. The cell where that row and column meet is the product. So 7 × 8 = row 7, column 8 = 56. Because multiplication is commutative, the grid is symmetric about the diagonal, 7 × 8 and 8 × 7 land on the same product, which is why only half the grid really needs memorising.

Patterns worth noticing

PatternWhat it looks like
SquaresDown the diagonal: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144
NinesThe digits of every multiple of 9 add up to 9 (9, 18, 27 … 108 → 1+0+8 = 9)
FivesEvery multiple of 5 ends in 0 or 5
Elevens (1-9)Doubled digits: 11, 22, 33 … 99
Even × evenAlways lands on the same even column and row, useful for checking a guess

Frequently Asked Questions

Where does a 1-20 multiplication chart get used?

Two-digit multiplication, area and volume problems, fractions with denominators up to 20, and algebra work. It is the practical upper limit for a printed wall chart, beyond 20 the grid gets too dense to scan.

How is a 20×20 chart different from a 12×12 table?

Only in size. The 20×20 adds rows and columns 13 to 20, so it covers products up to 400. Everything already true of the smaller table, the symmetry, the squares on the diagonal, still holds.

What is the fastest way to use a 20×20 chart?

Locate the larger factor down the left column, slide across to the smaller factor in the top row, and read the meeting cell. For 17 × 14 that is row 17, column 14 = 238.

Do I need to memorise the 13 to 20 rows?

No. Most curricula require fluent recall only up to 12. Rows 13-20 are usually looked up or worked out from known facts (17 × 14 = 17 × 10 + 17 × 4).
