Translate a PowerPoint Presentation into Chinese (Simplified)

What Simplified Chinese changes on a slide

Chinese is written without spaces between words and needs two to three times fewer characters than English or other European languages. Each character, however, fills a full square, much wider than a Latin letter, so the space a line takes on the slide barely changes. The bullet “Shorter delivery times” becomes 缩短交货时间: six characters, a line of similar length.

• Line breaks: Chinese can wrap between almost any two characters. A title you split by pressing Enter in the source keeps that break, which then lands at a random point in the Chinese sentence.
• Full-width punctuation: ，。：；？！ each take the width of a character, with no space before or after. Titles of reports or publications go between 《》.
• No capitals, no plurals: an all-caps title loses its effect, so emphasis comes from size or weight. Chinese has a single plural category: “3 slides” is 3张幻灯片, with a measure word and no plural marker.
• Italics: Chinese fonts usually have none, so characters get slanted artificially and read poorly. Use bold or colour instead.
• Numbers and dates: Chinese counts in 万 (ten thousand), so 1.5 million is 150万; a date reads 2025年3月14日.

Fonts: where Chinese decks usually go wrong

Calibri, Arial and most corporate typefaces contain no Chinese characters. Once the text is Chinese, PowerPoint borrows a substitute font from whatever computer opens the file: the look shifts from machine to machine, line heights change, and on a computer with no Chinese font the text shows as empty boxes.

A PowerPoint theme keeps separate fonts for Latin text and East Asian text. Before uploading, or straight after delivery, set a Chinese font for the theme’s East Asian text, for instance Microsoft YaHei or DengXian on Windows. Brand names, figures and acronyms left in Latin letters keep using the Latin font, so your visual identity survives on those elements.

Manuce replaces the text but does not pick fonts for you: the file’s own fonts stay in place. If the deck will circulate in mainland China or Singapore and must display reliably, share a PDF exported from a computer that has your chosen Chinese font.

What Manuce returns, and what stays in the source language

Manuce translates the text on every slide: titles, placeholders, text boxes, shapes, shapes inside groups and tables. You get your original .pptx back with the same theme, images, shape positions, animations and transitions; only the text is replaced. A Word version, a PDF and plain text come with it, handy for a Chinese-speaking reviewer who does not use PowerPoint.

Not translated at present:

• Speaker notes: if a Chinese-speaking colleague presents, their prompts stay in the source language.
• Charts and SmartArt: axis titles, legends and labels keep the original language, leaving a Chinese slide with, say, an English chart.
• Slide masters: a “Confidential — do not distribute” footer set in the master stays untranslated on every slide.
• Text inside images such as screenshots or exported diagrams.

A paragraph mixing several formats takes the formatting of its start. Chinese word order differs anyway, so a word you bolded has no equivalent position: reapply emphasis to the right Chinese term. Text box sizes are not recalculated; with Chinese the issue is less overflow than the line height of a substitute font, and any autofit set in PowerPoint still applies. Manuce does not provide sworn or certified translation.

Preparing the file before upload

• Simplified or Traditional: Simplified serves mainland China and Singapore. For Taiwan or Hong Kong, choose Traditional Chinese, handled as a separate language.
• SmartArt: convert it to ordinary shapes so its text is translated like any other shape.
• Charts: move the chart title into a text box and plan to retype axes and legends in Chinese after delivery.
• Masters: move any wording you need translated out of the master and onto the slides.
• Titles: remove manual line breaks so the Chinese can wrap on its own.
• Notes: if the presenter needs them, paste them into a Word document and have it translated separately.

The quote appears on upload, based on the exact word count of the source file; Chinese carries a ×1.6 coefficient. The free sample, one paragraph translated at your chosen level, lets you judge tone and terminology before paying.

Checking the Chinese version

1. Open the .pptx on a computer with a Chinese font, and ideally on a second one: no empty boxes should appear.
2. Look through autofit boxes: text shrunk to an unreadable size is fixed by widening the box.
3. Search for half-width commas and colons (, :) and stray spaces between characters.
4. Check amounts converted to 万 and dates in 年月日 order.
5. Ask a Chinese-speaking reader to confirm product names: keep the brand in Latin letters or use an established Chinese name.
6. Reapply bold to key terms in paragraphs that had mixed formatting.

In practice

1. Choose Simplified or Traditional Chinese according to your audience’s region.
2. Convert SmartArt to shapes and move translatable text out of the slide master.
3. Upload the .pptx and review the quote and free sample.
4. Download the .pptx, Word, PDF and plain-text versions.
5. Set a Chinese theme font and check every slide displays correctly.
