Photoshop: how to resize multiple artboards?

Question

Is there a way / script / workaround to re-scale multiple artboards including their contents (not just the canvas size)?

Ie. I have a PSB with 10-15 artboards. Each artboard is 1242 x 2208 and need to scale each one up to 1440 x 2560.

When I press ctrl+alt+i I get the Image size panel, but this shows me the whole master document size (size of all the artboards and the spaces between them combined).

I've seen many variations of this questions across many boards but haven't found a decent answer.

Answer 1

From iPhone 6/6S/7 PLUS size to Android's larger resolution screen.

You're probably going to have to increase the size of the entire image by the amount of difference. Luckily they're both 16:9 aspect ratios.

Hit CTRL+ALT+I and scale up by a percentage of 1.15942028985507.

This should leave you with all artboards at the right size.

Answer 2

For Photoshop you can try my script: "Transform with style".

Features:

• Intuitive control. Just transform layers as usually
• Works with multiple layers simultaneously
• Supports layer effects and shape styles
• Keeps proportions by default
• Possibility to change the settings in the script (true/false values inside the file)

Answer 3

i know... quite old ;)

1. select multiple artboards in the layers palette
2. select the "artboard tool" (shortcut "V", behind the "move tool")
3. use the context menu (at the top) and change the width/height values
