Why is social media so important?
In the age of visual marketing, the first impression determines the length of stay of the user. Using the wrong size or vertical ratio of the picture can cause serious damage to the brand image:
- Autocrop problem: If the picture is not proportional, social platforms automatically cut edges, which may lead to the loss of key text or product displays.
- Fuzzy and stretching: The images that are over-referral are forced to be magnified by the platform, resulting in pixels and very unprofessional.
- Load balance: While high resolution is good, excessive over-speculation can lead to documents being overloaded, affecting the speed of loading at the mobile end and even causing upload failure.
- Algorithm preference: Platforms (e. g. Instagram Reels or TikTok) prefer to push to match their full screen ratio (9:16) The first and second editions of the original text are available at www.un.org/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/sc/s/sc/sc/s/sc/sc/sc/sc/sc/sc/s/sc/sc/sc/

As the screen ratio of mobile devices becomes more diverse, we recommend that the following principles be followed:
- Zone awareness: Making TikTok or Reels When video is used, it is important to keep key elements (titles, CTA) in the centre area, avoiding the bottom description and right-hand interactive button areas.
- PNG superior to JPG: For designs containing text, Logo or large area pure colour, using PNG format is effective in avoiding the multiplicity of compacted colours.
- Fits the "dark mode": Consider your head and the performance of Logo in a dark background, and add light colour to the side, if necessary.
