# minimumInteritemSpacing The minimum spacing (in points) to use between items in the same row or column. ``` var minimumInteritemSpacing: CGFloat { get set } ``` ## Discussion If the delegate does not implement the [`collectionView(_:layout:minimumInteritemSpacingForSectionAt:)`](/documentation/AppKit/NSCollectionViewDelegateFlowLayout/collectionView(_:layout:minimumInteritemSpacingForSectionAt:)) method, the flow layout object uses the value of this property to set the spacing between items in the same line. For a vertically scrolling layout, the value represents the minimum spacing between items in the same row. For a horizontally scrolling layout, the value represents the minimum spacing between items in the same column. The layout object uses this spacing only to compute how many items can fit in a single row or column. The actual spacing may be increased after the number of items has been determined, as illustrated in [Figure 1](/documentation/appkit/nscollectionviewflowlayout/1402872-minimuminteritemspacing#1965632).  The default value of this property is `10.0`. --- Copyright © 2026 Apple Inc.
