300 DPI vs 600 DPI Scan: Scanning Tips For The Best Results


Scanning Tips For The Best Results

What is the difference between a 300 DPI and 600 DPI scan?

Which is the best DPI setting? Which is the best resolution for photos? If you’ve ever asked these questions, you aren’t alone.

Generally, the best DPI setting depends on what you plan on doing with your photos – whether it’s to print them out, make digital copies, or share them online. This article will explain the differences between 300 DPI and 600 DPI (the most common DPI settings) and their specific purposes. 

If you’ve already scanned your old photos, send them over to Image Restoration Center! With our professional restoration services, even the most damaged photograph will look new again.

Understanding Digital Photos And Scanning

Scanning Tips For The Best Results

Before we explain the differences between 300 DPI and 600 DPI, it’s essential to know the basics of digital imaging. In this section, we cover need-to-know information about digital photos and how your flatbed scanner works.

Digital Images

Digital images are made up of many pixels with three values: red, green, and blue (RGB). When millions of these colored pixels merge in a grid, that creates your digital image. So when you save a digital photo, you’re actually saving an array of pixels that combine to form the image.

Scanners & DPI

When scanning a photograph, scanners “capture” the physical photo or document by recording it as a grid of pixels. In other words, the more pixels used to record the digital photo or document, the more detailed it becomes. 

This measure of details on a scanned image is called the resolution. Image resolution on the screen is calculated in pixels per inch (PPI), while the measure for print is dots per inch (DPI). 

Most photographs, documents, and images are scanned at 300 DPI or 600 DPI, with the DPI representing the number of dots for every inch scanned. For example, scanning at 300 DPI means each inch will be made up of 300 dots.

How DPI Settings Affect The Digital Image Quality

Having higher DPI values doesn’t automatically make your photographs better. While it’s true that higher resolution scans will turn out more detailed, cranking up the DPI can’t add more detail to the original photo. 

What a higher DPI does is make your digital photo larger. For example, if you scan a 4×6 photo at 300 DPI, you’ll receive a digital image that’s 1200 pixels wide and 1800 pixels tall. Scanning the same photo at 600 DPI will give you a digital photo that’s 2400 pixels wide and 3600 pixels tall. 

Larger DPI scan resolutions are great if you want to display or print larger photographs. For example, a 4×6 photo scanned at 300 DPI will still look great as a printed image in its original size, but it will lose overall quality if you order a larger print. Meanwhile, the same photo scanned at 600 dots per inch can still look good as larger prints.

Another thing to keep in mind is that higher resolutions have a higher pixel count – meaning larger file sizes.

How Do I Choose My Scanning Resolution?

Scanning Tips For The Best Results

While it may be tempting to always use the highest resolution, scanner DPI setting, or pixel count possible, we don’t recommend it. To save time and storage space, you should think about your intended use of the photos rather than just going for the maximum resolution every time. 

For example, if you’re just planning to upload the photo to social media or view them on a computer screen, 150 dots per inch/pixels per inch is fine. However, if you’re planning to take them to a print shop, you should go for a higher resolution. 

Generally, a 600 DPI scan is the best image resolution and pixel count for paper photographs. High resolutions above 600 DPI are better suited for professional archive work due to the longer scan time and larger storage requirements. 

If you have your own scanning device, we recommend choosing 600 DPI over 300 DPI as your default resolution because of the negligible differences between scan times and file size.

Tips To Get The Best Photo Scans

If you have a scanning device at home, scanning photos yourself is pretty easy. However, there are a few things that you need to keep in mind if you want the best picture quality. Here are four tips you can follow to get the best-looking scans.

Clean Your Scanner

A clean scanner glass gives you the best scan results. Rather than having to do clean-up afterward, it’s best to get the best scan quality possible from the get-go. 

To clean your scanner bed properly, wipe it with a dry microfiber cloth. Never use tissue paper because it might leave debris and scratch the scanner glass surface. If your scanner glass has persistent smudges, you can try dampening your cloth before wiping again.

Ensure Your Photos Are Dust-Free

Another key to good scan results is a clean photo. 

If you’ve just pulled out old pictures from an album, they may be covered in dust. To clean old photos, use compressed air to blow the dust off them. As with the scanner bed, never use paper tissues and definitely don’t use water to clean them because it may create even more damage.

Old pictures may also have creases, fold marks, or printing defects on them. Don’t try to fix them – this may cause more damage. Leave them as-is when scanning, and edit them out afterward using editing software.

Scan In Color

As a rule of thumb, every photo you scan should be scanned in color. Even when you’re scanning sepia and black & white photos, you’ll get a better result when scanning in color as color scans record more detail and preserve as much quality as possible. Moreover, while you can turn colored scans into grayscale, you can’t do the reverse.

Scan Multiple Images At Once

If you have several photographs that need scanning, consider scanning in batches to save time. Try placing your smaller photographs together on the glass bed with about a quarter-inch of space, then scan all of them at once. After scanning, you can simply crop each of them out using editing software and save them as individual pictures.

Why Hire A Professional Photo Restorer?

Even with your own scanning device, it may take a while before all your photographs are scanned. Moreover, the quality isn’t guaranteed. If you want the best results and to not have to worry about resolutions or pixel count, we suggest that you seek professional image restoration services to scan your photos for you.

Image Restoration Center offers photo scanning services to any client who wants their images restored. We create high-resolution scans and turn them into precious keepsakes that will last for years to come. 

Restore Your Old Photos In Three Simple Steps

Our image restoration services are affordable and simple! To get your old photographs looking like new again, all you need to do is follow these three steps.

Step 1: Upload Your Image

First of all, send your images to us in digital format. You can do this with a digital scanner or simply by taking a picture of it with your phone. While phone pictures usually do the trick, high-quality scans help us do better work. Here’s how to choose the best file format to scan your photos at.

Once you have the scan, you can upload it to our secure servers.

Step 2: Wait While We Work Our Magic

The second step is to simply wait. Our team will pore over your old photo and – with advice from our historical advisors – colorize and restore them into high-quality digital files. Most of the time, this process takes 1 to 3 days.

Step 3: Receive Your Restored Photos

Lastly, once the restoration work is done, we’ll send the files to you via email. If you have feedback or other requests, you can always message us on your website. 

We also provide photo printing services delivered right to your door! While your prints may take a while to arrive, you’ll have high-quality printed photos on your doorstep before long.

Generally, 600 DPI scans are your best bet if you’re scanning family photographs for preservation. A lower resolution like 300 DPI will result in less image detail, but it will save you time and storage space.

If you have a stack of old family photographs waiting to be scanned and revitalized, Image Restoration Center is here to help! Send us a restoration request today, and you’ll receive the finished work in just 1-3 days.

  1. A museum has accepted a very large Altar my grandfather carved into its permanent collection. There are photos dating back to the 1910s and 1920s relating to the Altar.
    The museum has requested “high quality scans” of the photos for their files.
    How is it best to obtain the scans?
    Please keep in mind that these photos are held by many different people.
    How can I best request these photos be sent to me (or the museum) in a manner easy for the individual having the photo but in a form suitable for the museum archives?
