Navigating the filesystem in macOS Finder provides four distinct viewing modes: Icon View, List View, Column View, and Gallery View. While each presentation mode offers distinct benefits for browsing assets, users frequently encounter an annoying inconsistency: adjusting the icon size, grid spacing, label text size, or sort order in one directory often fails to apply to any other folder on their Mac. When you open a secondary directory or external drive, Finder reverts to generic system defaults.
Fortunately, macOS includes a dedicated Show View Options configuration panel that allows you to finely customise typography, thumbnail previews, column widths, and folder size calculations, and then permanently commit those rules as the global template across all directories. This guide explains how to customise folder view options and set global defaults in macOS Finder.
Why Customise Finder View Options?
Fine-tuning your Finder presentation parameters provides several immediate workflow and organisation advantages:
- Standardised Visual Consistency: Enforcing a single default view mode (such as List View or Column View) eliminates jarring layout shifts when moving across different directories.
- High-Density File Browsing: Reducing icon dimensions and text sizes allows you to view hundreds of files on a single display without continuous vertical scrolling.
- Instant Folder Size Calculations: Enabling “Calculate all sizes” allows you to identify storage-hogging directories at a glance in List View without manually checking Get Info panels.
- Optimal Grid Spacing: Expanding icon grid spacing in Icon View prevents long file names from clipping or overlapping adjacent desktop icons.
How to Open the View Options Panel in Finder
The View Options inspector dynamically adapts its controls based on which of the four view modes is currently active in the foreground Finder window:
- Open any folder in Finder.
- Switch to the viewing mode you wish to configure (press Cmd + 1 for Icon, Cmd + 2 for List, Cmd + 3 for Column, or Cmd + 4 for Gallery).
- Open the options panel by pressing the keyboard shortcut Cmd + J, or by clicking View in the top menu bar and selecting Show View Options.
- A floating inspector window will appear anchored to the active Finder window.
Customising Options for Icon View (Cmd + 1)
When Icon View is active, the View Options panel presents several spatial adjustments:
- Icon size: Drag the slider from 16×16 up to 512×512 pixels to scale desktop and folder thumbnails.
- Grid spacing: Adjust the distance between icons to prevent long file names from truncating.
- Text size: Change the font size of file labels between 10 pt and 16 pt.
- Label position: Choose whether text labels appear Bottom (under the icon) or Right (to the right of the icon).
- Show item info: Displays metadata beneath the label, such as pixel dimensions for image files or track counts for audio folders.
- Show icon preview: Renders live graphical previews of PDFs, images, and video thumbnails rather than generic application icons.
- Sort by / Clean up by: Choose an automated arrangement order, such as Name, Date Modified, Date Added, or Kind.
Customising Options for List View (Cmd + 2)
List View is the preferred viewing mode for administrative tasks, log audits, and data analysis. In the View Options panel (Cmd + J):
- Always open in list view: Check this box to force the current folder to always open in List View regardless of how you navigated into it.
- Browse in list view: Keeps subfolders expanding cleanly inline with disclosure triangles.
- Calculate all sizes: (Highly Recommended) By default, Finder leaves folder sizes blank in List View, showing dashes (
--). Checking this box forces Finder to calculate and display exact folder sizes in megabytes and gigabytes in real time. - Show columns: Tick or untick checkboxes to display columns for Date Modified, Date Created, Date Last Opened, Size, Kind, Version, and Comments.
Customising Options for Column View (Cmd + 3)
Column View offers smooth hierarchical directory traversal. In the Column View Options panel:
- Text size: Adjust the typography scale for directory names.
- Show icons: Toggle small file type icons next to directory names.
- Show preview column: Enables or disables the rich metadata preview pane that appears on the right edge when a file is highlighted.
How to Apply Custom Settings as Global Defaults
By default, adjustments made in the View Options panel apply strictly to the specific folder you currently have open. To propagate these settings across your entire Mac:
- Configure all your preferred options (such as icon size, font size, calculate all sizes, and column selections) inside the View Options window (Cmd + J).
- At the very bottom of the View Options window, locate the button labelled Use as Defaults.
- Click Use as Defaults.
- From this point forward, every newly created folder and any folder that has not been individually overridden will automatically adopt your custom layout rules.
How to Reset Folder View Overrides to Default
If a specific directory (such as Downloads or Documents) was previously customised and refuses to adopt your new global default:
- Navigate into that specific folder.
- Press Cmd + J to open View Options.
- Hold down the Option key (⌥) on your keyboard.
- The Use as Defaults button at the bottom of the window will transform into Restore to Defaults.
- Click Restore to Defaults to clear custom per-folder metadata and re-inherit the global configuration.
Troubleshooting Common Finder View Options Issues
“Use as Defaults” Button Is Greyed Out
The “Use as Defaults” button will appear disabled if the currently active window is a virtual Spotlight search results query, a smart folder, or the special All My Files / Recents view. Navigate to a physical directory (such as your Home folder or Macintosh HD root) to set system-wide defaults.
Folder Sizes Still Showing Dashes in List View
Calculating directory sizes across drives with millions of files requires indexing time. If dashes still appear, verify that “Calculate all sizes” is checked in View Options, and give macOS a few moments to traverse local APFS snapshots and directory tables.
Frequently Asked Questions
Does “Calculate all sizes” slow down my Mac?
On modern Macs equipped with fast Apple Silicon processors and APFS solid-state drives, calculating folder sizes has negligible performance impact because APFS maintains instant file size metadata. However, over slow network shares or mechanical USB drives, calculating sizes can cause noticeable folder loading delays.
Can I assign different view defaults for external USB drives?
Yes. macOS stores per-folder view preferences inside hidden .DS_Store metadata files located in each directory. You can set a specific USB drive to always open in Icon View while keeping your internal system drive set to List View.
How do I close the View Options window?
Simply click the red close circle in the top-left corner of the floating inspector, or press Cmd + J again to toggle the panel closed.
