# How can I make the vertical space to be of the same length as the horizontal space when creating a photo grid collage with Contact Sheet in Photoshop?

I use Photoshop -> File -> Automate -> Contact Sheet II to create a photo grid collage. The vertical spaces are much larger than the horizontal spaces:

How can I make the vertical spaces to be of the same length as the horizontal spaces, when creating a photo grid collage with Contact Sheet II in Photoshop?

Contact Sheet II settings:

Images used:

• Images need to be promotional if you wish them to have the same gutter. Contact sheet won't "stretch" images vertically to keep a gutter dimension. Oct 11, 2022 at 5:58
• @Scott thanks, sorry what is a promotional image? I googled it a bit and didn't see a definition. I was hoping the contact sheet could organize images of same size so that the horizontal spacing between images is the same as the vertical space between images Oct 11, 2022 at 6:05
• ehh. sorry... auto fill.. I meant proportional. And Contact Sheet is filling your predetermined 8x10 sheet with as many images as it can fit.. not varying the sheet dimensions in order to keep gutters and images the same size. Oct 11, 2022 at 6:07
• Proportional does not mean "same size". It's mean each of your 6 images, vertically, need to fill the space available once (0.014" * 10) is subtracted from your sheet height - 10". So [ 10 - (0.014 *10) / 6 = 1.643" ] -- Each of the images needs to be 1.64" in height to maintain your desired gutter and use 10" vertically. Oct 11, 2022 at 7:01
• Math is wonky in that comment above.. overcompensated for the gutters.. it's better in the actual answer `:)` Oct 11, 2022 at 7:10

Contact sheet will not "Stretch" images to fill spaces.

If you wish all gutters to be the same, one needs to do the math and figure out the proper image size to fit the desired sheet size.

This means each of your 6 images, vertically, need to fill the space available once the gutter has been accounted for. So ...

``````10" / 6 = 1.666" minus gutter (0.014) = 1.652"
``````

And you can do the same for the horizontal...

``````8" / 4 = 2 minus gutter (0.014) = 1.986"
``````

Each of the images needs to be `1.986" x 1.652"` in size to maintain your desired gutter and use an 8" x 10" sheet.

Contact Sheet II chooses vertical spacing so that the images are vertically spread across the document. As a result, one can reduce the image height to reduce the vertical spacing, e.g. from 10 inches to 9.5 inches in this example:

The vertical spacing is now more similar to the horizontal spacing:

One could compute which height results in the vertical spacing being equal to the horizontal spacing. Or just say empirical and try a few values.
