# stride(ofValue:) Returns the number of bytes from the start of one instance of `T` to the start of the next when stored in contiguous memory or in an `Array`. ``` static func stride(ofValue value: borrowing T) -> Int ``` ## Parameters `value` A value representative of the type to describe. ## Return Value The stride, in bytes, of the given value’s type. ## Discussion This is the same as the number of bytes moved when an `UnsafePointer` instance is incremented. `T` may have a lower minimal alignment that trades runtime performance for space efficiency. The result is always positive. When you have a type instead of an instance, use the `MemoryLayout.stride` static property instead. ``` let x: Int = 100 // Finding the stride of a value's type let s = MemoryLayout.stride(ofValue: x) // s == 8 // Finding the stride of a type directly let t = MemoryLayout.stride // t == 8 ``` --- Copyright © 2026 Apple Inc.
