Video thumbnails for overseas markets need to be created differently than those for domestic markets.
However, thumbnails for YouTube videos aimed at overseas viewers need to be created differently than thumbnails for videos aimed at domestic viewers .
For example, if you create your video in the same way as a video for Japan, the thumbnail image may look strange to overseas viewers.
Overseas audiences have different preferences depending on the country and region.
- Preference for color and contrast.
- Do you like calm expressions or flashy expressions?
You also need to choose a font that sounds natural for each country or region you target.

7 ways to create compelling thumbnails for your international YouTube videos

Now, let's take a look at some specific points to consider when creating thumbnails for YouTube videos aimed at overseas audiences.
1. Create YouTube video thumbnails in 16:9
![]()
When creating thumbnails for videos aimed at overseas audiences, it's important to have basic knowledge about YouTube thumbnails.
YouTube video thumbnail format :
- Resolution: 1280x720 pixels (aspect ratio 16:9)
- Image file formats: JPG, GIF, PNG, etc.
- File size: 2MB or less
It is as follows.
The image aspect ratio is 16:9.
Even if the image resolution is large, it will be resized when uploaded , so there is no problem if it is large.
You can also create and upload it at the same resolution as the video, 1920x1080 pixels.
2. Use fonts other than those included with the OS
![]()
When creating thumbnails for videos aimed at overseas audiences, it is very important to choose the appropriate font for each target country or region .
In particular, if you are using Windows, it is not recommended to use standard fonts.
*There is no problem with Mac, but we recommend installing fonts other than the standard ones.
Have you ever felt uncomfortable with the fonts used in advertisements created by overseas companies?
When overseas companies create advertisements for Japan, they often end up using standard Windows fonts such as MS Gothic, Meiryo, and Yu Gothic.
When Japanese companies create advertisements for the Japanese market, they rarely use the standard Windows fonts.
When creating YouTube video thumbnails for overseas audiences, choosing a font at random can often end up being the same thing.
To avoid such mistakes, it is recommended to research what fonts are preferred in your target country or region .

3. Use large font sizes

When creating a thumbnail for a YouTube video, it's important to use a large font size .
We recommend using either the left or right half of your thumbnail as space for text so that anyone can understand the content of your video at a glance.
Large font sizes limit the number of characters you can use , and it can often be difficult to come up with the right words for YouTube videos aimed at overseas audiences.
In such cases, we recommend using generative AI services such as ChatGPT, Claude, or Google Gemini.

Another technique is to give instructions like this and then choose the one you like.
4. Choose extra-bold font weight

The thickness (weight) of the text used in YouTube thumbnail images is also important.
Choose the thickest font weight possible, such as "Extra Bold" or "Black."
There are some expressions that use thin letters, but these are for advanced users.
At first, you can't go wrong by using the boldest font available.
5. "Bullet-pointed letters" are best
![]()
When creating a YouTube thumbnail image, it is recommended that you use "outlined text" for all text.
Enclosed characters are characters that have an outline around them , as shown in the image.
Not only is it easier to read than typing text individually, but it also makes a strong impression on the viewer and makes an appealing impression.
It is also recommended to double the border, as shown in the image .
Almost all professionally created video thumbnails use outline text, which gives the impression that the video is highly polished.
6. Add a border in the image color around the image
![]()
A key to making your YouTube thumbnail image more attractive is to add a border around the image .
This is especially important when the thumbnail background is a photo .
As shown in the image, surrounding the thumbnail with a thick line makes it stand out, increasing the chances of it being clicked (tapped) among many other thumbnails.
Color is also important when adding borders.
Deciding on an image color for your YouTube channel and using that color will give your viewers a consistent impression.
If you don't have a specific image color, it's safe to use a strong color such as red or black.
7. Slightly tilt the text to the right
![]()
When placing text, it is important to make sure it slopes slightly to the right .
A slight upward slope gives the image a dynamic feel , making it a more eye-catching thumbnail.
8. Cut out and place an image of a person
![]()
If you have a photo of a person you can use as your thumbnail, we recommend cropping the photo and overlaying it on a background image .
Photos of people can make a strong impression on your audience.
You can maximize the effect of portraits by placing the photo large, as in this image.
When placing a photograph of a person, adding a shadow (using "Stylize → Drop Shadow" in Illustrator) or a white border around the image (using "Layer Effects → Border" in Photoshop) can make it even more appealing.
When creating thumbnails for marketing purposes such as product promotion or branding, it is recommended to crop the product photo and arrange it in the same way.
