Simplified vs Traditional Chinese: Which Do You Need?
One of the most important decisions in any Chinese translation project is choosing between Simplified Chinese and Traditional Chinese. The choice depends on your target audience and region.
| Feature | Simplified Chinese | Traditional Chinese |
|---|---|---|
| Used In | Mainland China, Singapore, Malaysia | Taiwan, Hong Kong, Macau |
| Character Count | ~6,500 characters | ~13,000+ characters |
| Complexity | Fewer strokes per character | More strokes, more complex |
| Common Use | Government, education, digital content in mainland China | Government, media, publishing in Taiwan and Hong Kong |
| Digital Platforms | Baidu, WeChat, Weibo, Taobao | Google (Taiwan/HK), Yahoo Taiwan, LINE |
Simplified Chinese was introduced in the 1950s to improve literacy rates in mainland China. It uses fewer strokes per character, making it easier to learn and write. If your target market is mainland China or Singapore, Simplified Chinese is the right choice.
Traditional Chinese retains the original character forms used for centuries. It is the standard in Taiwan, Hong Kong, and Macau. If your audience is in these regions, or if you're translating historical, cultural, or literary content, Traditional Chinese is essential.
At Ulatus, our Chinese translation services cover both scripts. We match every project with translators who are native to the target region, ensuring that vocabulary, idioms, and cultural references are locally appropriate, not just linguistically accurate.
How Our Chinese Translation Process Works
Every Chinese translation project at Ulatus follows a structured process designed for accuracy, efficiency, and client satisfaction.
