How to Rotate the Ruler in Snipping Tool (Windows 11)

The Snipping Tool in Windows 11 hides a small virtual ruler that does more than sit flat across your screenshot. You can turn it to any angle, lock it in place, and draw a clean straight line along it. The control for this is not obvious, which is why so many people assume the ruler only works horizontally.

Quick answer: Add the ruler to your capture, hover the mouse pointer over it, then scroll the mouse wheel up to rotate clockwise or down to rotate counterclockwise. On a laptop, slide two fingers up or down on the trackpad.

Rotate the Ruler in Snipping Tool with a mouse

Open the Snipping Tool and capture the area you want to work on. You can press Win + Shift + S to start a new snip, then choose your capture mode.

Bring up the ruler. In current builds, click the three-dot menu (⋯) and choose Show ruler. In Snipping Tool version 11.2305 and earlier, click the Ruler button in the toolbar. The keyboard shortcut Ctrl + R also toggles the ruler (older versions used Alt + L).

Move your mouse pointer over the ruler, near the center where the angle is shown. The middle of the ruler displays the current angle, which starts at 0 degrees.

Scroll the mouse wheel. Scrolling up rotates the ruler clockwise, scrolling down rotates it counterclockwise. The angle readout updates as you turn it, so you can stop at the exact value you need.

Drag the ruler to reposition it, then pick a pen and draw along its edge to make a straight line at that angle. Click the ruler button again to remove it when you are done.

📍

The ruler rotates around the top-left tip of your mouse pointer, not around the ruler’s own center. Keep that in mind when you want a precise pivot point.

Rotate the Ruler on a laptop trackpad or touchscreen

If you do not have a scroll wheel, the gesture is just as simple. Move the pointer over the ruler first, then place two fingers on the trackpad and slide them up to rotate clockwise or down to rotate counterclockwise. On a touchscreen tablet, the same two-finger swipe over the ruler changes its angle.

Fix: Ruler won’t rotate when you scroll the mouse wheel

A common snag is that the ruler sits there and refuses to turn no matter how much you scroll. This happens because the ruler only responds to the wheel when Windows is allowed to scroll a window your pointer is hovering over, even if that window isn’t selected. Turning on one setting usually fixes it.

Press Win + I to open Settings.

Go to Bluetooth & devices, then select Mouse.

Under the Scrolling section, turn on Scroll inactive windows when hovering over them.

Go back to your snip, hover over the ruler again, and scroll. It should now rotate as you move the wheel. If it does, the fix worked.

What you cannot rotate

The protractor is the other measurement tool in the Snipping Tool, and it does not rotate. You don’t need to spin it anyway, since you measure an angle by placing it over the vertex and drawing along the curve. The Snipping Tool also won’t rotate the captured image itself, though you can still crop it down to the area you want.

With the ruler angled exactly where you need it, every line you draw runs perfectly straight along that edge, which is handy for marking up screenshots, lining up design elements, or measuring across an image at a slant.
