Solution: How to Get Rid of Extra 1px While Exporting an Artboard in Adobe Illustrator?

At work in a public library, I design posters and flyers for events quite a lot. I often need to export artwork, created in Adobe Illustrator, to be of a specific size. Especially the ones for screens and TVs of which the units are pixels.

For example, an image for a local TV, a size of 1920 x 1080 pixels (HDTV).
The procedure is quite straightforward. You create an artboard of the specific size (1920 x 1080 px), make an illustration, export the artboard via “Export As” under “File -> Export” menu, check “Use Artboards” and export it as .jpg or .png. Not a big deal, right?

But! More often than not when I check the size of the exported image I notice the annoying unwanted extra pixel to either width or height.

See the screenshot below.

After a bit of online research, I found out what the problem is.
When I start a project most of the time I just create a default file with default artboard size AND default units. In my case the artboard size is A4 and the units are in millimeters.

Of course, I want the units to be in pixels (or points) when I do stuff for screens, not for print. Now notice the XY position of the exact same artboard when I change the units of the documents from millimeters to points (“File” -> “Document Setup” -> “Units”).

This is the root of the problem. Now even when I change the size of the artboard to my desired size (in my example 1920 x 1080 px), the Y position stays the same (297.64 px). And those decimals cause the problem for that extra pixel to the exported file.


When you export your artwork for the screens (units in pixels), always make sure the XY positions of the artboard are whole numbers. In this specific case, I just delete those .64 decimals, so the position would be X: 0 px, Y: 297 px.

Just a little note. Make sure you change the document’s units first and after that (when you have units in pixels) delete those unwanted decimals.

That’s it, I hope this info comes in handy to someone. 🙂

Take care.
