Frequently asked questions

How do I copy the ■ shape?

Click the big ■ at the top of the page to copy it. Geometric shapes are plain text characters, so they paste into documents, spreadsheets, slides and posts.

Why does the shape look different in my app?

Each font draws geometric shapes slightly differently — sizes and sharpness vary, but the character is the same everywhere.

Why does ■ sometimes show as a box or question mark?

The box (called tofu) means the device or font viewing it has no drawing for U+25A0 (Black Square). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.

Is the Black Square free to use?

Yes. ■ is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
