How to add a square grid as a layer?

Another way to recycle an existing grid made out of paths for a larger map than originally anticipated is to double it in size, copy the layer, and shift the second one half a square up and half a square to the right. Et voilà, a new grid 4x as large as the original, with the same mesh size!

Also, there are Photoshop brushes out there that have a pre-made grid. This one's pretty nice. Brushes are by definition raster data though, so you can't easily scale them up/down without messing up the width of the lines. So use with caution!

Yep! It is something I made as well and I forgot to mention.

I think to do something FOR WELL once is the only solution to be versatile "later".

Thank you for sharing this trick. I almost forgot about it

Here is a very easy way I've made grid lines for a map as a new layer.

First. Open up a spreadsheet app like Excel or Calc. Set the column width and row height to match each other; ie 1inch x 1inch.

Take a screenshot.

Paste that as a new layer. Use the magic wand to get rid of the white space and then get rid of the rest of your screenshot leaving behind a grid.

Hope that helps!
