7 Things To Know About K-Weights

  1. The ‘heavier’ a piece of content is, the slower it will load. That’s why k-weight is such an important consideration for any sort of digital design work.
  2. Ad networks and websites limit the k-weight of ads they allow. This limit will be documented in their ad specs – *always* read it before designing your ads.
  3. Energuide.be estimates that total energy used for a 1mb email emits about 20g of CO2. This means that lower K-Weights are also good for the environment!
  4. The K-Weight limit of ads is broken down into two parts: 1. Initial Load – how much can be loaded immediately (usually 200kB); 2. Sub Load – how much can be loaded after the rest of the webpage (usually around 500kB)
  5. According to httparchive, webpages averaged around 500KB in July 2011 but have ballooned to around 2MB by July 2019.
  6. A favicon should weigh no more than 300 bytes ideally.
  7. According to Cloudflare, conversion rates increase by around 0.5% for every 1 second faster a page loads. Lower K-Weights can increase revenue!
