Today’s Question: Is there a way to increase the size of the thumbnails for the layers of my images on the Layers panel in Photoshop?
Tim’s Quick Answer: Yes! You can adjust the thumbnail size for the Layers panel as well as the Channels panel by choosing “Panel Options” from the panel popup menu found at the top-right corner of either of these panels. Then choose the desired thumbnail size and click OK to close the dialog and apply the change.
More Detail: It can be very helpful at times to have a large thumbnail for each of your layers on the Layers panel in Photoshop. Of course, at other times it can also be helpful to have smaller thumbnails, or even no thumbnails at all, such as when you are working on a document with a particularly large number of layers.
Fortunately, several options are available, ranging from “None” for no thumbnails, all the way through “small”, “medium”, and “large” sizes for the thumbnails. Note that each of the sizes is represented by a graphical icon rather than by any text. But you can choose one of the sizes in the applicable “Panel Options” dialog and click OK to apply the change. And, of course, you can switch back and forth between the different sizes for the thumbnails based on what is most helpful for your current task.
