I have been testing a vertical writing feature for **Times New Roman**. Since the original font does not support vertical orientation, I added the vertical writing feature and specified a uniform height of **1136**. However, during the vertical writing preview, the English characters do not display at all.

Initially, I thought it might be a font-specific issue, so I tested it with another font, but the problem persisted. Interestingly, the vertical display works perfectly fine in **Photoshop**. I suspect this might be a software bug; I am currently using the latest version ( **15.0.3048** ).

Additionally, I have a technical question regarding the **Automatic Metrics Wizard (Fixed Height)** for adjusting vertical spacing. Specifically, how are the values for **Vertical Offset** and **Advance Height** determined? The official manual is quite vague on this.

As a user from Asia, vertical writing functionality is essential for us. Through testing, I’ve found that the **Advance Height** represents the character space height I need to set. However, I am unsure how to calculate the other value. I am currently setting a vertical height for Times New Roman to integrate it into a Chinese font that utilizes vertical characters. Since the Chinese font height is **1136** , I set the Times New Roman unit height to **1136** as well. Given this, how should the **Vertical Offset** be calculated?

Thanks for the detailed report.

The font display problem is likely limited to FontCreator’s vertical preview rather than the font data itself. We will investigate that.

Regarding **AutoMetrics → Fixed Height** :  
**Advance Height** is the vertical advance to the next glyph.  
The **vertical origin** is based on the glyph’s top plus its **top side-bearing**.

So if you want a glyph to fit inside a vertical cell of **1136** units, a good starting point is:

**Top side-bearing = (1136 - (yMax - yMin)) / 2**  
**Vertical Offset = yMax + Top side-bearing**

Or combined:

**Vertical Offset = yMax + (1136 - (yMax - yMin)) / 2**

Please note there is usually no single perfect value for Latin glyphs in vertical writing. In practice, you may still need a small optical adjustment, especially for uppercase letters, punctuation, and mixed Latin/CJK text.

Let us know if these assumptions are correct.
