Here are a few options for the WordPress post_tag description for “名片尺寸 (Ming Pian Chi Cun – Business Card Size)” in Traditional Chinese, ranging from concise to slightly more detailed, depending on your needs:

**Option 1: Concise & Direct (Suitable for quick reference)**

* **Description:** 名片的標準尺寸。 (Ming pian de biao zhun chi cun. – Standard size for business cards.)

**Option 2: Slightly More Informative (Adds a bit more context)**

* **Description:** 常見名片的大小規格，方便設計和印刷。 (Chang jian ming pian de da xiao gui ge, fang bian she ji he yin shua. – Common size specifications for business cards, convenient for design and printing.)

**Option 3: Including Dimensions (Most Detailed – Provides very specific information)**

* **Description:** 名片的標準尺寸，通常為 90mm x 54mm 或 55mm。 (Ming pian de biao zhun chi cun, tong chang wei 90mm x 54mm huo 55mm. – The standard size for business cards, usually 90mm x 54mm or 55mm.)

**Option 4: Focusing on Design & Usage (Emphasizes relevance to design)**

* **Description:** 了解名片尺寸，幫助您設計出合適的名片，確保印刷品質。 (Liao jie ming pian chi cun, bang zhu nin she ji chu he shi de ming pian, que bao yin shua pin zhi. – Understanding business card size helps you design suitable business cards and ensures printing quality.)

**How to choose:**

* **Prioritize clarity:** Choose the description that is easiest for your target audience to understand.
* **Consider your audience:** Are your readers primarily looking for exact dimensions, or for general information on design?
* **Content surrounding the tag:** The surrounding content/topic on your website also influences your decision. If you have a lot of content design-related posts, then choose option 4.
* **Character limits:** Keep in mind WordPress’s often-limited character counts for descriptions.

I recommend starting with **Option 2** or **Option 4** for the best balance of information and conciseness, and then adjusting based on your specific needs.
