+These same formatting conventions apply to pattern matching. F# style values consistent formatting:
+
+```fsharp
+// ✔️ OK - Consistent formatting for expressions and patterns
+let result = Some(value)
+
+match result with
+| Some(x) -> x
+| None -> 0
+```

 You may need to pass arguments to a function on a new line as a matter of readability or because the list of arguments or the argument names are too long. In that case, indent one level:

+Pattern matching formatting should be consistent with expression formatting. Do not add a space before the opening parenthesis of pattern arguments:
+
+```fsharp
+// ✔️ OK
+match x with
+| Some(y) -> y
+| None -> 0
+
+// ✔️ OK
+match data with
+| Success(value) -> value
+| Error(msg) -> failwith msg
+
+// ❌ Not OK, pattern formatting should match expression formatting
+match x with
+| Some (y) -> y
+| None -> 0
+```
+
+However, do use spaces between separate curried arguments in patterns, just as in expressions:
+
+```fsharp
+// ✔️ OK - space between curried arguments
+match x with
+| Pattern arg (a, b) -> processValues arg a b
+
+// ❌ Not OK - missing space between curried arguments
+match x with
+| Pattern arg(a, b) -> processValues arg a b
+```

 If the expression on the right of the pattern matching arrow is too large, move it to the following line, indented one step from the `match`/`|`.
