Selecting and Importing Fonts
Customizing the fonts in your Nextion interface is crucial for enhancing readability, aesthetics, and user engagement. Nextion Editor offers a wide range of fonts to suit various design requirements. Here’s a detailed guide on selecting and importing fonts:
Selecting from Predefined Fonts
Nextion Editor comes with a comprehensive library of predefined fonts. To select a font:
- Click the "Font" tab in the editor toolbar.
- In the "Font" drop-down menu, browse through the available fonts.
- Preview the fonts by hovering your mouse over each option.
- Choose the font that best aligns with your design concept.
Importing Custom Fonts
If you wish to use a font that is not part of the predefined library, you can import it into Nextion Editor:
- Download the desired font file in TTF or OTF format.
- Navigate to the "File" menu and select "Import Font."
- Browse to the location where the font file is saved and click "Open."
- The imported font will now appear in the "Font" drop-down menu.
Font Files and Compatibility
Nextion Editor supports importing font files in the following formats:
| Font Format | Compatibility |
|---|---|
| TTF (TrueType Font) | Fully compatible |
| OTF (OpenType Font) | Partially compatible (basic characters only) |
Note that certain fonts may contain special glyphs or characters that are not supported by Nextion displays. It is recommended to preview the imported font before finalizing the design to ensure optimal rendering.
Changing Font Properties for Individual Objects
To customize font properties for specific objects, follow these steps:
-
Select the object: Click on the object to select it.
-
Open the Properties panel: Click on the "Properties" tab in the left-hand panel.
-
Locate the "Font" section: Scroll down to the "Font" section within the Properties panel.
-
Modify font properties: Adjust the following settings within the Font section:
Setting Description Font Select the desired font family. Size Adjust the font size in pixels. Color Choose the font color. Bold Enable bold font style. Italic Enable italic font style. Underline Enable underlined text. -
Apply changes: After making the desired adjustments, click "Apply" or "OK" to save the changes.
Modifying Font Size
Within the “Font” section of the Nextion Editor menu, you will find the “Size” parameter. This parameter determines the size of the font in pixels. By default, the font size is set to “16”, but you can adjust it according to your preference. Increasing the value will enlarge the font, while decreasing it will make the font smaller.
Alignment
The “Alignment” parameter allows you to control the horizontal alignment of the text. The available options are “Left”, “Center”, and “Right.” These settings affect the position of the text within the designated area on the TFT display.
Advanced Font Customization
For more advanced font customization, you can utilize the “Font Table” feature. This feature enables you to define custom fonts by specifying the character mapping, glyph width, and height. By incorporating a custom font into your project, you can achieve a unique look and enhance the overall user experience.
Font Table Structure
The Font Table is organized as a two-dimensional array, where each row represents a character and each column corresponds to a pixel in the font. The following table illustrates the structure of the Font Table:
| Column | Pixel Value |
|---|---|
| 0 | MSB of Left Edge |
| 1 | LSB of Left Edge |
| 2 | MSB of Right Edge |
| 3 | LSB of Right Edge |
| … | … |
| n | Nth Pixel |
To define a custom font, you will need to specify the character mapping, which assigns each character to a specific row in the Font Table, and the glyph dimensions, including the width and height of each character.
Adding International Character Support to Fonts
To expand the font’s capabilities and allow for the display of international characters, follow these steps:
1. Open the Font File
Locate and open the TrueType Font (.ttf) file in a font editor such as FontForge or FontLab VI.
2. Add Glyphs for Missing Characters
Identify the missing international characters and create corresponding glyphs for them using the font editor’s glyph design tools. Ensure the glyphs comply with the Unicode standard.
3. Assign Unicode Code Points
Assign the appropriate Unicode code points to the newly created glyphs. This will associate the glyphs with their corresponding Unicode characters.
4. Generate and Embed the Font
After adding the required glyphs and assigning Unicode code points, generate the updated TrueType Font file. Make sure the font has a Unicode encoding to support international characters.
5. Install the Updated Font
Install the updated font on your system. Once installed, the font will be available for use in Nextion Editor and will support the display of international characters.
Enhanced Guide for Glyph Design
Glyph design requires attention to detail and adherence to Unicode standards. Here are additional tips:
* Use the “Unicode Character Table” provided by the Unicode Consortium for reference.
* Create glyphs that are consistent with the existing style of the font.
* Ensure the glyphs are visually distinct and unambiguous to avoid character confusion.
* Set the glyph’s unicode value to the corresponding Unicode code point.
* Export the glyphs in a format compatible with the TrueType Font (.ttf) file.
| Required Unicode Code Points | Corresponding Characters |
|---|---|
| U+00E0 | à |
| U+00E8 | è |
| U+00F2 | ò |
| U+00F9 | ù |

Best Practices for Typography in Nextion HMI Designs
Use a Consistent Font Family
Select a font family that aligns with the overall design and purpose of your HMI. Stick to one or two primary fonts for consistency.
Choose Legible Fonts
Ensure that the selected fonts are easy to read, especially at small sizes. Avoid decorative or overly stylized fonts that may hinder readability.
Optimize Font Size
Adjust font sizes according to the available space and target viewing distance. Use larger fonts for headings and smaller fonts for body text.
Provide Adequate Line Spacing
Add sufficient space between lines of text to improve readability and prevent visual clutter. A line spacing of 1.5-2 times the font size is generally recommended.
Consider Text Orientation
Determine the most suitable text orientation (horizontal, vertical, or angled) based on the layout and available space.
Apply Contrast
Use contrasting colors for text and background to enhance visibility. Avoid using light text on a light background or dark text on a dark background.
Limit Text Length
Keep text concise and to the point. Avoid long paragraphs or sentences that may overwhelm the user.
Utilize Text Alignment
Align text to the left, right, or center to create a clean and organized appearance. Left alignment is the most common and is recommended for longer text.
Font Usage Considerations
The following factors should be considered when selecting fonts for Nextion HMI designs:
| Factor | Considerations |
|---|---|
| Font License | Ensure compatibility and compliance with the font’s license. |
| Font Availability | Verify that the font is available on the Nextion editor or can be imported. |
| Font Quality | Choose fonts that are well-designed and suitable for the HMI environment. |
| Font Size Range | Select fonts with a wide range of sizes to accommodate different text requirements. |
| Font Style | Consider whether the font style (regular, bold, italic) complements the overall design. |
