What are the dimensions for maximum picture width and height in the Bootstrap 4 grid class col-4? Additionally, can you provide some tips on minimizing image bl

Hey there! I am trying to arrange 3 screenshots in 3 separate columns in one row, resembling steps 1, 2, and 3. I want them all to have the same size. Can you advise on the maximum width and height I should use before they start getting stretched or compressed? I will be using bootstrap grid col-4. Additionally, do you know of a way to reduce the blurriness of pictures? My images are slightly larger than necessary, causing some blur; for example, 300px width by 300px height.

Answer №1

When it comes to optimizing images for the web, the key factor is the pixel dimensions of your screenshots. Smaller pixel dimensions result in smaller width and height before the image becomes too pixelated. You can effectively optimize pictures for the web using tools like Photoshop or online resources.

In the past, there was a general rule that 72dpi/ppi was ideal for web use, while 300dpi/ppi was best for print. However, dpi/ppi is not as critical for web usage unless you are targeting retina displays, which require higher quality images. Media queries can help adjust picture resolution based on device pixel ratios.

For example:

@media 
(-webkit-min-device-pixel-ratio: 1.5), 
(min-resolution: 144dpi){ 
    /* Retina-specific adjustments here */
}

More information on retina displays and examples can be found here.

When working on web design or development, having a design guide with specific image dimensions for each page is useful. It's crucial to consider the overall memory size of the image, aiming for optimized images under 200kb in size. Heavy images can significantly impact page performance by increasing loading times.
