I made a file size 320*370, however they become 321*370 while I export them into png?? Things happen to every files unless there is only one artboard in the file. Always 1 px more from what I originally set. Any idea how can this be fixed?
2Is your artboard exactly on the pixel or is it ioffset?– joojaaDec 8, 2016 at 10:50
2There is a chance your inage is not pixel perfectly aligned, and the extra pixel is an anti alias column.– RafaelDec 8, 2016 at 21:44
My exports were also 1 pixel off in some of my images. Aligning my artboards to the pixel grid as joojaa recommended resolved the issue.– Bill CampbellOct 29, 2017 at 22:20
This is caused when the artboard is on decimal pixel value on X and Y, and when the size of the artboard is decimal as well Make sure that your artboards are located on integer values on the X and Y axis and has integer Width and Height.
Try to rearrange them putting a integer value between them! Cheers!
This is the answer that solved my problem, and should be the accepted answer. Apr 2, 2020 at 14:34
Your art is outside your artboard. Export don't use artboard size but the draw a square that contain all boxes. So if for example you have text box and your text is 320 but the text box is 324 then the export will be 324.
Use "safe for web" as is use artboard size when saving for png.

- Make sure each object you want to export is in separate artboards.
- Select all the objects.
- Go to File -> Export Selection.
- Go to 'Artboards' tab, Tick off the 'Include Bleed' box under the artboard range.
- Set the artboard range and choose your desired format.
- Click 'Export Artboard'.
Done! Now every images that you exported will be as the same as the artboard sizes you set.
All of the answers here are partial. For consistent results you need to use all the techniques listed here:
Your artboard must be exactly on X and Y coordinates (eg: x:270 y: 179, not x:269.96 y: 179.21). Turn on your pixel grid (View > Pixel Preview) and turn on Snap To Pixel (View > Snap to Pixel) when drawing new artboards, or just type round numbers into the Artboard Properties panel (for x, y, width and height).
Either make sure none of your artwork could bleed outside the edges of your artboard OR (better) turn OFF "Include Bleeds" when you use Export for Screens. Remember that for most strokes, if the stroke aligns with the edge of your artboard, chances are it actually spills outside the boundaries of your artboard because strokes by default are centered on the line.
If all the above isn't working for you, you can always fall back to Save for Web (Legacy) where you can clearly see the pixel dimensions while exporting and there are no surprises.
Does the same thing happen whether you SAVE AS or if you SAVE FOR WEB? The SAVE FOR WEB is much better because it gives more options (exact sizing and image quality). And SAVE FOR WEB offers previews of the final PNG with pre-calculated file size.
