How can I zoom to fit Window?

[Design_Optimizer]

when I have tiled windows, or floating windows customly arranged, I would like to zoom each design to fit its own window.

Hi there,

Command/Control +0 lets you fit the image in the window.

Does that help your workflow?

If not here are multiple zoom view option in Photoshop while working with multiple images:

Match only zoom

Open one or more images, or open one image in multiple windows.
Choose Window > Arrange > Tile to display the images edge to edge.
Select the Zoom tool, and then do one of the following:
Select Zoom All Windows in the options bar, and then click one of the images. The other images zoom in or out the same relative amount.

Choose Window > Arrange > Match Zoom. Hold down the Shift key and click one of the images. The other images zoom in or out at the same magnification.

Match only location
Open one or more images, or open one image in multiple windows.
Choose Window > Arrange > Tile.
Do either of the following:
Choose Window > Arrange > Match Location.

Select the Hand tool, select Scroll All Windows in the options bar, and then drag to view another area in one of the images.

Match zoom and location
Open one or more images, or open one image in multiple windows.
Choose Window > Arrange > Tile.
Choose Window > Arrange > Match All.

Without Match All command (top), and with Match All command (bottom) selected

Select the Zoom tool or the Hand tool.
Select one of the images, hold down the Shift key, and click in or drag an area of an image. The other images are magnified to the same percentage and snap to the area you clicked.

Thanks,

Hi Akash

Thanks for your replay, but it doesn't help me. My designs have different dimensions, so I need to zoom to different zoom levels for each design. Here I have zoomed manually in each window to make the designs fit. I'd like to do this with just one command (Like "Fit all in windows").

Zoom to fit All. Designs have different dimensions, thus different zoom levels is required

You may try the Window > Arrange > New window option.
If you want to arrange the windows, choose Window > Arrange and then choose "Tile".as it displays windows edge to edge. As you close images, the open windows are resized to fill the available space.

Time ago (like in photoshop CC) there was some plugin that you could purchase and they were dedicated to do this task, now there isn't a tool that do this and i feel that adobe think that you should be trained in scripting or do this manually
