With the smart phones becoming cameras, there is a plethora of ways and devices to take good quality, and high resolution images. Today’s iPhone & Android devices can easily take 5 or 8 or 12 Megapixel images, and simple digital cameras start at 8, 12 or 16 megapixels or more.
This is more than sufficient to print huge A0 or A1 sized Poster or even larger images.
The problem is that when you open an image in Photoshop, it shows the image size in pixels. Many of us are not sure how to size it so that we can print it at a photo print shop, or on your new Photo Printer.
This recent image that I took with my Canon 70D show up like this.
In Photoshop, Go to Image > Image Size to see the size of the image you have opened in Photoshop.
As you can see, we have enough pixels to print a large print. We have 5472 pixels (width) and 3648 pixels (height). The image is huge (57.1 MB in size), and if you print it just like this, it will take 76 inches width, and 50 odd inches in height. That’s really huge.
So how does it help you in deciding how big will be the print. And if you want to crop the image to size it better, or to remove some unwanted elements, how can you be sure that it will print properly in the paper size you have chosen.
If you notice the bottom of the screenshot, Photoshop has checked by default, the setting to constrain the proportions. This means that if you change the width, it will automatically adjust the height to make sure the image looks appropriate, and not distorted. Similarly, if you change the height, the width changes automatically.
So let’s say we want to print an image on a standard 8 by 10 inch frame. This means 8 inch width, and 10 inches height.
So if we change the document size Width to 8 inches, the Height automatically changes to 5.333 inches. That’s not what we want.
And if we change the document size Height to 10 inches, the Width automatically changes to 15 inches.
This defeats the purpose, as we need the image size of 8 inches by 10 inches, and not anything else.
So how do we get around this problem. Enter the Crop Tool of Photoshop.
The Crop Tool in Photoshop looks like 2 right angle crossing each other.
Click on it. The top bar below the menu will change to something like this.
Now key in 10 in in the Width box, and 8 in in the Height box. Here in stands for Inches.
So far, nothing has changed. Now click inside the image, and drag. A box border will begin to emerge. This is the size of a 8 inches by 10 inches image. You can drag and drop it anywhere. What ever is in the box, will be the right size to print nicely on a 8 by 10 paper.
Once you are happy with what is in the box, press Enter. The image will be cropped (Resized).
Now if you examine the Image Properties, you will notice that the image shows a resized image of size 8 inches by 10 inches, or 10 inches by 8 inches, depending on what you had selected in the Crop Toolbar. I had selected 10 by 8 as my orchid image is landscape.
With this method of using the Crop tool in Photoshop, you will get perfect sized images which will print off well, without any distortion.
You can create images for any size.
Some common Paper Size and their dimensions in Inches is given below for your benefit.
Larger number are height. Format used is Width x Height.
- A0 (A Zero) size: 33.11 x 46.61 inches.
- A1 size: 23.39 x 33.11 inches
- A2 size: 16.53 x 23.39 inches
- A3 size: 11.69 x 16.53 inches
- A4 size: 8.27 x 11.69 inches
Hope this will help you to crop the images to the right size, and print in full glory.
