How to Make an NYT-Style Crossword

Updated

An NYT-style crossword is a 15×15 grid (21×21 on Sunday) with 180° rotational symmetry, no unchecked squares, no words shorter than three letters, a full-interlock layout, and a consistent theme that appears in the longest answers. Word counts are capped near 78 for a themed 15×15, 72 for a themeless, and 140 for a 21×21. This guide covers the conventions that give those puzzles their feel, and it is separate from the general how to make a crossword puzzle walkthrough.

Rules in this guide are drawn from the New York Times's published submission guidelines and widely documented editorial conventions. The NYT calls its guidelines a living document, so as of October 2026, check the official page before you submit.

What sizes do NYT-style crosswords use?

Day Grid Type
Monday to Thursday 15×15 Themed
Friday and Saturday 15×15 Usually themeless
Sunday 21×21 Themed, larger

Difficulty rises from Monday to Saturday. Monday is the easiest. Sunday is a larger puzzle that is roughly midweek in difficulty. Thursday often carries a trick, such as a rebus or an unusual grid gimmick. Gridsmith supports 15×15 and 21×21 grids, which cover the standard daily and Sunday sizes.

What are the grid rules?

These are the hard structural rules:

  1. 180° rotational symmetry. The block pattern looks the same when rotated half a turn. See crossword grid rules for the variants.
  2. No unchecked squares. Every white square is part of an across answer and a down answer.
  3. Minimum answer length of three letters. No 2-letter answers.
  4. Full interlock. All white squares form one connected region.
  5. Black squares in moderation. Heavy blocking is considered a sign of weak construction.

How many words can an NYT-style crossword have?

Per the NYT's submission guidelines, the word-count maximums are:

Puzzle Maximum words
Themed 15×15 78
Themeless 15×15 72
21×21 (Sunday) 140

The guidelines note these can be exceeded slightly when the theme requires it, at the editor's discretion. Lower counts mean longer words and a harder fill. Most themeless grids run well under the cap because they showcase long, lively entries.

How does an NYT-style theme work?

A weekday theme usually places a handful of long answers that share one wordplay rule, with an optional revealer.

For idea generation, see crossword theme ideas. In Gridsmith, Theme mode marks which entries are theme answers.

What counts as good fill in an NYT-style puzzle?

Good fill is mostly common, recognizable words and phrases, with as few "crosswordese" or obscure abbreviations as possible. The NYT guidelines ask that answers that appear in crosswords far more than in real life be kept to a minimum. Practical targets:
