What is the difference between ⊂ and ⊆?

⊂ means "proper subset of" — every element of the left set is in the right set, and the two sets are not equal. ⊆ means "subset of or equal to" — the left set can also be identical to the right set.

How do I type the subset symbol in LaTeX?

Use \subset for the proper subset symbol (⊂) and \subseteq for subset-or-equal (⊆). The superset equivalents are \supset and \supseteq.

What is the HTML entity for the subset symbol?

The named entity is ⊂ for ⊂ and &sube; for ⊆. You can also use the numeric entities ⊂ and ⊆, or the hex forms ⊂ and ⊆.

Why does the subset symbol not display correctly?

Some older fonts or systems lack full Unicode math coverage. Try a font with broad Unicode support (like Arial Unicode MS, Segoe UI, or a system default sans-serif) or use the LaTeX/HTML code instead of the raw character.

What is the symbol for "not a subset of"?

It is ⊄ (U+2284), typed in LaTeX as \not\subset or \nsubseteq for the not-subset-or-equal variant (⊈).

Summary

Copy the subset (proper and subset-or-equal) symbols along with their Unicode, HTML entity, and LaTeX codes.

How it works

Browse the symbol cards for the subset and superset variants you need.
Click the large symbol to copy just the character.
Click any code chip (Unicode, HTML entity, or LaTeX) to copy that specific code.
Paste the copied value into your document, markup, or LaTeX source.

Use cases

Insert ⊂ or ⊆ into a math paper, slide deck, or documentation.
Grab the LaTeX command for a subset symbol without memorizing it.
Find the HTML entity for a set-theory symbol for a web page.
Look up the Unicode codepoint of a subset or superset glyph for a font or icon check.
Copy the "not a subset of" or "proper superset" variants for a discrete math assignment.
