+title: minContains and maxContains
+description: Learn how to use the 'minContains' and 'maxContains' keywords in JSON Schema to ensure that arrays contain a specific number of elements.
+keywords: array, minContains, maxContains, validation, JSON Schema

+
+# minContains and maxContains
+
+Previously, we learned how to use the `contains` keyword to ensure that an array contains **at least one element** that matches a specific *subschema*. 
+
+However, there are scenarios where we need to ensure that an array contains a specific number of elements that match a *subschema*.
+
+You can use the `minContains` and `maxContains` keywords along with `contains` to specify the minimum and maximum number of elements that an array must contain to be valid.
+
+## Example
+
+The following example demonstrates how to use the `minContains` and `maxContains` keywords to ensure that an array contains exactly 2 elements that are less than 10.
+
+```json
+{
+  "type": "array",
+  "contains": {
+    "type": "number",
+    "maximum": 10
+  },
+  "minContains": 2,
+  "maxContains": 2
+}
+```
+
+## Task
+
+
+```json highlightLineStart={4}
+{
+  "name": "John Doe",
+  "age": 30,
+  "workedHours": [9, 10, 8, 11]
+}
+```
+
+Our employee has field called worked hours. We want to ensure that the `workedHours` array contains **at least 2 elements** that are **greater than or equal to 8 and less than or equal 12**. Modify the schema given to you in the side editor to apply this constraint.
