To adjust text size in Microsoft Word in late 2025, you can use the ribbon menu, a floating toolbar, or quick keyboard shortcuts to resize your content. First, highlight the text you want to change, then navigate to the Home tab and locate the Font Size box; you can either click the dropdown arrow to select a preset number or type a custom size (between 1 and 1638 points) directly into the box and press Enter. For rapid adjustments, click the Increase Font Size button (a large "A" with an up arrow) or the Decrease Font Size button (a small "A" with a down arrow) located right next to the number box. On Windows, the fastest method is using the keyboard: press Ctrl + ] to increase the size by one point at a time, or Ctrl + [ to decrease it; alternatively, you can use Ctrl + Shift + or Ctrl + Shift + to jump between the standard preset sizes in the dropdown menu.
