Photoshop Tip: What are PPI and PPCM?

Written By Paul Changion Senior On 19 May 2016

When should I use the PPI and PPCM image size setting in Photoshop?

The short answer is never!

We receive a lot of calls from confused clients when it comes to image settings in their editing software. For those of you that are technically minded, read this article and this article. For the rest of you, it’s simple really, this is what you need to know:

1. PPI stands for pixels per inch and PPCM stands for pixels per centimeter in PhotoShop
2. These are measurements of the resolution or pixel density of your screen and become useful when talking about the size and quality of a printed image
3. At PrintWild we ask for 300ppi images at the desired print dimensions that you would like, although when this is not possible we get unbelievable prints out of files submitted as low as 150ppi (this is not acceptable for less forgiving mediums such as high-quality acrylic prints)
4. 150 pixels per inch is around 60 pixels per cm and 300 pixels per inch works out at around 100 pixels per cm
5. What happens is we end up getting 300ppcm files that are huge i.e. around 500ppi, this unnecessarily large file takes longer to upload, is often incorrectly sized to those settings which don’t result in the best version of the original image

The takeaway here is, be aware of the difference between these 2 options, choose PPI as your Photoshop default and submit files min 150ppi (preferably 300ppi) when working with PrintWild. If this is mumbo-jumbo to you then just submit whatever you have and we’ll take over from there, you’ll get a call from us if we feel your image is not high resolution enough for your chosen printed product.

Any questions, please don’t hesitate to contact us on 086 999 0233 and the designers in pre-production will be happy to chat further about your image quality or size queries.

Until then, keep it simple!

Fast, friendly and professional service. From placing the order online to reciving the order, which only took 5 days, I was updated regularly on my order throughout the process. The canvas prints and faceblocks are excellent quality. I highly recommend PrintWild, if your a professional photographer or just want to print some family pics. They are the best! Keep up the great work!

Thank you Printwild for helping me keep and display my memories. Printwild have such a user friendly website and the ordering process was so easy, simply upload your images.I was kept in the loop throughout the entire ordering process so knew when my photos were edited, being printed and ready. The customer service is amazing and the staff are super helpful. All my photos were sent for met to proof before they were printed and i was able to keep some text on one of my images as well. The courier was quick and i was given tracking details to follow my order. The photos arrived and WOW! The magnatots look like glass tiles and the quality of print on both the magnets and photoblocks is crystal clear. i was able to unpack and hang my photoblocks, which i'm now addicted to, straight away. Such wonderful ways of displaying lots of photos in a small space. i love it! Can't wait to put in my next order

As a pro photographer having shot around 500 weddings, it’s extremely important that our brides are happy with their Canvas photos. Every bride as well as other clients have praised the quality of all the products supplied by Printwild 💕 Besides the great products and excellent services, the staff from the top and across all the spectrums, are an absolute delight to deal with and make one feel special. Having dealt with Printwild for over a decade I highly recommend them.
