Pixel is a definite small area of illumination on a display screen. Many pixels combine to form a visual, an image which can be a website or mobile app. They are basically the smallest unit on a grid displaying an image. There is a linear relationship between the number of pixels and the quality of the image. In other words, more the pixels, better the quality.Pixel perfection is a keyword used by mostly design & development companies across the globe. It sets bench-marking standards in terms of the expected quality design output. Designing and Development are the core strength of any website or mobile application.Many times designers design the website or mobile application in Photoshop PSD format and later front end developers slice it to PSD to HTML. This is where pixel perfection becomes the defining parameter to set exact match, leading to higher quality & client satisfaction.As mentioned by Brandon Jones, “Perfect” means that every element of every design component is exactly as you want them to be in the final product.Customers encounter common problems when pixel perfection isn’t been considered by their development company. Few of them can be:

  • Imperfect Margins
  • Padding Issues
  • Inconsistent Font usage
  • Border and background inconsistency
  • Color mismatch
Pixel perfection takes place at several levels, whether someone is creating designs from the wireframes or creating HTML pages from the designs. It has to look the same exactly, down to every pixel.Pixel perfection implementation needs to be taken care at:
