Manage Collection View Cell Height Dynamic According To Text Label Data

Updated 31 July 2019


In most of the times we take label inside the collection view.  And we want the height of collection view exactly equals to label data height, because it will not look good if label data height is less than collection view cell, it will show a blank space and if label data height is more than collection view then it will truncate the data.

Here I am discussing about how to manage collection view cell height according to text label data.

Follow the steps :

Step 1: Go to Collection View cell class and create the outlet of label.

Step 2: Now go to MainViewController and create the outlet of collection view.

Step 3: Now create the extension to calculate the height of the label.


Step 4: Now Register the collection view cell so that we can use.

Step 5: After register the collection view cell write their All delegate and datasource method inside main controller class.

Step 6: Now your collection view cell height will automatically increase after calculating the height of label.



So please follow the above step and and if you have any issue or suggestion you can leave your query/suggestion in the comment section I will try to solve that.

      Use this extension
      extension String {
      func height(withWidth width: CGFloat, font: UIFont) -> CGFloat {
      let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
      let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSAttributedString.Key.font: font], context: nil)

      return ceil(boundingBox.height)
