Website Image Size
Here is a quick overview of some basic resolution concepts:
- PPI (pixels per inch) refers to how many pixels will appear in a single inch of any digital screen. PPI, also known as pixel density, is used to measure the clarity of images. The higher the PPI, the greater the detail will appear in the image.
- DPI (dots per inch) is another way to measure clarity but on paper. This is an important measurement for any printed versions of your logo, as it will determine the dots of ink.
- Resolution is the total number of pixels that will appear on the screen. It is always measured in both width and height, so it will always be written as 500 x 500 pixels (px), for example.
- Bytes refer to the actual file size and can be measured in kilobytes (KB), megabytes (MB), and gigabytes (GB).
Easier to reduce the size
Keep in mind that it’s much easier to start with a large size and go smaller, rather than trying to expand one that is too small. You can use an image resizer to help make adjustments.

It is important to note that these are general guidelines, and the ideal image size will vary depending on the website layout and design. Additionally, it is extremely important to optimize all images for website performance by resizing and compressing them.
Image file types
JPEG and PNG are the two most commonly used image formats for websites.
- JPEG is ideal for photographs and images with many colors. Such as the hero, background, and blog images.
- PNG is ideal for images with fewer colors and transparent backgrounds. Such as your logo images.
Both formats can be compressed and are compatible with all modern browsers.
Landscape image format
Landscape images are optimal for websites due to their visual appeal. The horizontal orientation seamlessly complements the widescreen displays of modern devices, providing a natural and expansive canvas for showcasing images and graphics. Landscape images align with the conventional left-to-right reading pattern, ensuring users can effortlessly absorb content without excessive scrolling.
This format allows web designers to present images with greater detail and context, enhancing the overall storytelling capabilities of a website. Moreover, landscape images tend to occupy more screen real estate, making them particularly effective for capturing attention and creating memorable visual experiences for site visitors. Ultimately, landscape image format contributes to a more aesthetically pleasing and user-friendly web design and is essential for retaining and engaging audiences in the digital age.
