Make Finder Window Columns Resize to Fit Filenames

ByMike Moffit

Column view in the Finder has an annoying tendency to either show overly wide columns that waste space or truncate long filenames, forcing you to drag a column divider to see more of the name. In macOS 26.1 Tahoe, Apple added an option to the Finder’s View Options window that automatically adjusts column widths to display the longest visible filename in each column. To activate it, choose View > Show View Options with a column-view window frontmost, then select the “Resize columns to fit filenames” checkbox. If you’re running macOS 13 Ventura through macOS 15 Sequoia, this option is hidden, but you can enable it by pasting this command into Terminal: defaults write com.apple.finder _FXEnableColumnAutoSizing -bool YES; killall Finder. (Change YES to NO to revert the change.) Alternatively, the free TinkerTool 10 utility provides a graphical toggle for these older operating systems—look for “Automatically adapt to file name widths in column mode” in the Finder section.

Social Media: Tired of truncated filenames in the Finder’s Column view? macOS 26.1 Tahoe adds a simple checkbox to auto-resize columns—and you can enable the same feature in earlier macOS versions with a quick Terminal command or free utility.

    I had a great trip up to Jasper, GA to pick up the 2003 Victory motorcycle. I took almost all two-lane roads and the weather cooperated although it was a bit chilly in the mornings. It got busier as I headed south in Florida but all in all it was a great way to spend the weekend.

    When you form a “corporation”, if you tear down the word to its Latin base, it means to “form a body”. My high school latin teacher would be proud. As a body in society, a business has a bigger footprint than any individual. We have buildings, we consume resources, we generate waste and we have a huge impact on peoples lives. With that larger footprint comes a larger responsibility and that is the basis for our commitment to always measure our success by the triple bottom line of People, Planet and Profit.
