+# Length
+
+Validate the length of a string or iterable.
+
+```rust
+# extern crate fortifier;
+# use fortifier::Validate;
+#
+##[derive(Validate)]
+struct User {
+    #[validate(length(min = 1, max = 256))]
+    name: String
+}
+```
+
+## Types
+
+### String
+
+- [`str`](https://doc.rust-lang.org/std/primitive.str.html)
+- [`String`](https://doc.rust-lang.org/std/string/struct.String.html)
+
+Validate the amount of characters ([`chars`](https://doc.rust-lang.org/std/primitive.str.html#method.chars)) in a string.
+
+### Iterable
+
+- [`[T]` (slice)](https://doc.rust-lang.org/std/primitive.slice.html)
+- [`[T; N]` (array)](https://doc.rust-lang.org/std/primitive.array.html)
+- [`BTreeSet`](https://doc.rust-lang.org/std/collections/struct.BTreeSet.html)
+- [`BTreeMap`](https://doc.rust-lang.org/std/collections/struct.BTreeMap.html)
+- [`HashSet`](https://doc.rust-lang.org/std/collections/struct.HashSet.html)
+- [`HashMap`](https://doc.rust-lang.org/std/collections/struct.HashMap.html)
+- [`IndexSet`](https://docs.rs/indexmap/latest/indexmap/set/struct.IndexSet.html) (requires feature `indexmap`)
+- [`IndexMap`](https://docs.rs/indexmap/latest/indexmap/map/struct.IndexMap.html) (requires feature `indexmap`)
+- [`LinkedList`](https://doc.rust-lang.org/std/collections/struct.LinkedList.html)
+- [`Vec`](https://doc.rust-lang.org/std/vec/struct.Vec.html)
+- [`VecDeque`](https://doc.rust-lang.org/std/collections/struct.VecDeque.html)
+
+Validate the amount of entries in an iterable.
+
+## Options
+
+### Equal
+
+The length should be equal to the specified expression.
+
+```rust
+# extern crate fortifier;
+# use fortifier::Validate;
+#
+##[derive(Validate)]
+struct User {
+    #[validate(length(equal = 2))]
+    country_code: String
+}
+```
+
+### Minimum
+
+The length should be equal to or greater than the specified expression.
+
+```rust
+# extern crate fortifier;
+# use fortifier::Validate;
+#
+##[derive(Validate)]
+struct User {
+    #[validate(length(min = 1))]
+    name: String
+}
+```
+
+### Maximum
+
+The length should be equal to or less than the specified expression.
+
+```rust
+# extern crate fortifier;
+# use fortifier::Validate;
+#
+##[derive(Validate)]
+struct User {
+    #[validate(length(max = 256))]
