Aspect Ratio

All print sizes are NOT equal

Persnickety Prints

Aspect Ratio determines image dimensions. When shooting, you’ll most likely need to crop the image to fit your final print project. It’s always best to know what final dimensions are needed before shooting.

Let’s talk about aspect ratio.

The aspect ratio is expressed as two numbers separated by a colon (x:y). A common misunderstanding is that x and y represent actual length and height. This is false; they actually represent the relation between width and height.

The aspect ratio of the 35mm frame is 3:2. Most fx and dx digital SLRs, regardless of sensor size or megapixels, default to the 3:2 aspect ratio.

A 3:2 image will print a full frame 4×6 print with little to no cropping. Most point and shoot cameras + smart phones are set in the 4:3 ratio, best for 3×4, 6×8 and 12×9 prints.

Avoid Unexpected Cropping:

    1. Shoot wide
    2. Adjust/crop your images in a photo editing program prior to printing
    3. At Persnickety, we can do the cropping for you, choose crop option 1.

While adjusting an image layer in Photoshop using the move tool, hold the shift key to lock proportions.


      1. Shoot wide to give yourself more wiggle room for possible cropping
      2. Don’t stretch or squish images to fill space for print
      3. Let Persnickety Prints do the work. Printing hundreds of images, but you don’t have the time or energy to crop each one? Let us do the work! Certified lab techs look at every image before, during and after printing. Lab techs will visually crop images using best judgement for the print size selected.
