# Get array dimensions and size of a dimension in Julia – size() Method

The `size()` is an inbuilt function in julia which is used to return a tuple containing the dimensions of the specified array. This returned tuple format is (a, b, c) where a is the rows, b is the columns and c is the height of the array.
Syntax: size(A::AbstractArray) or size(A::AbstractArray, Dim) Parameters:
• A: Specified array
• Dim: Specified dimension
Returns: It returns a tuple containing the dimensions of the specified array.
Example 1:
 `# Julia program to illustrate  ``# the use of Array size() method `` ` `# Finding a tuple containing the dimension of ``# the specified 1D array A. ``A ``=` `[``5``, ``10``, ``15``, ``20``] ``println(size(A)) `` ` `# Finding a tuple containing the dimension of ``# the specified 2D array B of size 2*2 ``B ``=` `[``5` `10``; ``15` `20``] ``println(size(B)) `` ` `# Finding a tuple containing the dimension of ``# the specified 3D array C of size 2*2*2 ``C ``=` `cat([``1` `2``; ``3` `4``], [``5` `6``; ``7` `8``], [``9` `10``; ``11` `12``], dims``=``3``) ``println(size(C)) `
