Seeding Order Calculator

Work out seeding order instantly with clear inputs, formula shown and shareable results.

About Seeding Order Calculator

Standard seeding pairs seed s against seed (bracket size + 1 - s) in the first round, so the top seed meets the lowest and the halves are balanced. The pairing rule is what keeps the best seeds apart until late rounds, and knowing your side of the draw matters more than your own seed number.

Formula

First round pairing

opponent seed = bracket size + 1 - your seed

Worked example

With the default values below, Seeding Order Calculator returns First round opponent seed of 12. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Seeding Order figure worked out?

opponent seed = bracket size + 1 - your seed. Standard seeding pairs seed s against seed (bracket size + 1 - s) in the first round, so the top seed meets the lowest and the halves are balanced.

Why does this matter?

The pairing rule is what keeps the best seeds apart until late rounds, and knowing your side of the draw matters more than your own seed number.

What do I need to enter?

Enter bracket size, your seed. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
