What was the size of the 2017 r/place canvas in pixels?

The 2017 r/place canvas measured 1,000 by 1,000 pixels.

That created a grid of one million individual pixel squares. Reddit users could change the color of one pixel at a time, then had to wait before placing another. The original experiment began on April 1, 2017, and turned a simple digital canvas into a huge coordination challenge involving thousands of online communities.

Participants organized flags, logos, memes, characters, and recreations of famous artwork. Communities often negotiated alliances or competed for territory, so the final image reflected both cooperation and conflict across Reddit. More than one million users contributed during the 2017 event, placing approximately 16 million pixels in total as parts of the canvas were repeatedly overwritten.

The larger dimensions associated with later editions can cause confusion. The 2022 version began at 1,000 by 1,000 but was later expanded to 2,000 by 2,000. The 2017 edition itself used the original one-million-pixel canvas, making 1,000 by 1,000 the canonical answer.
