Implementing Dutch Language Guidelines for International Software
Developing software for a global audience requires careful consideration of linguistic nuances. For applications targeting the Netherlands, adhering to the “Guidelines Nederlands” (Dutch Language Guidelines) is crucial for user experience and accessibility. This article delves into the practical application of these guidelines within software development, focusing on formatting, terminology, and cultural sensitivity to ensure your application resonates with Dutch-speaking users. We’ll explore concrete examples and techniques to seamlessly integrate these guidelines into your workflow.
This article will not cover the legal ramifications of not implementing accessibility standards, but rather focus on best practices. It is the developer’s responsibility to ensure that the software adheres to all applicable laws and regulations.

Date and Time Formats
Correctly formatting dates and times is essential for a localized Dutch user experience. The Netherlands predominantly uses the 24-hour clock and a specific date format that differs from other European countries and the United States. Ignoring these nuances can lead to confusion and a perception of unprofessionalism.Date Formatting
The standard date format in the Netherlands is dd-MM-yyyy (day-month-year). Using separators like hyphens is the norm, although periods are also sometimes used, especially in older documents. Avoid using slashes (dd/MM/yyyy), which are more common in other regions. Example 1: Correct Date Format// PHP example using the IntlDateFormatter
$date = new DateTime();
$formatter = new IntlDateFormatter('nl_NL', IntlDateFormatter::FULL, IntlDateFormatter::NONE, 'Europe/Amsterdam', IntlDateFormatter::GREGORIAN, 'dd-MM-yyyy');
echo $formatter->format($date); // Output: e.g., 26-10-2023
// Incorrect Date Format (US style)
$date = date("m/d/Y"); // Avoid this!
echo $date; // Output: e.g., 10/26/2023 (Incorrect for Dutch users)
Time Formatting
The Dutch use the 24-hour clock. Therefore, 1 PM is written as 13:00. Seconds are often omitted unless a high degree of precision is required. The colon (:) is the standard separator between hours, minutes, and seconds. Example 3: Correct Time Format// JavaScript example
const now = new Date();
const hours = String(now.getHours()).padStart(2, '0');
const minutes = String(now.getMinutes()).padStart(2, '0');
const time = `${hours}:${minutes}`;
console.log(time); // Output: e.g., 14:35
// Incorrect Time Format (AM/PM)
const now = new Date();
const time = now.toLocaleTimeString('en-US', { hour: 'numeric', minute: 'numeric', hour12: true }); // Avoid this!
console.log(time); // Output: e.g., 2:35 PM (Incorrect for Dutch users)
Combining Date and Time
When combining date and time, the standard format is to separate them with a space: dd-MM-yyyy HH:mm. Example 5: Correct Date and Time Combination// Python example
import datetime
now = datetime.datetime.now()
formatted_datetime = now.strftime("%d-%m-%Y %H:%M")
print(formatted_datetime) # Output: e.g., 26-10-2023 14:40
Number and Currency Formatting
Number and currency formatting are crucial for conveying numerical data accurately. The Dutch use different conventions compared to English-speaking countries, particularly regarding decimal separators and thousands separators. Incorrect formatting can lead to misinterpretations of values.Number Formatting
In the Netherlands, the period (.) is used as the thousands separator, and the comma (,) is used as the decimal separator. This is the opposite of the convention in English-speaking countries like the United States. For example, one thousand two hundred thirty-four and fifty-six hundredths is written as 1.234,56 in Dutch. Example 1: Correct Number Formatting// PHP example using number_format()
$number = 1234.56;
$formatted_number = number_format($number, 2, ',', '.');
echo $formatted_number; // Output: 1.234,56
// Incorrect Number Formatting (US style)
$number = 1234.56;
$formatted_number = number_format($number, 2, '.', ','); // Avoid this!
echo $formatted_number; // Output: 1,234.56 (Incorrect for Dutch users)
Currency Formatting
The Euro (€) is the currency used in the Netherlands. The currency symbol is typically placed before the number, with a space separating the symbol and the value. The same rules for number formatting apply to currency: the period (.) is the thousands separator, and the comma (,) is the decimal separator. For example, one thousand two hundred thirty-four euros and fifty-six cents is written as € 1.234,56. Example 3: Correct Currency Formatting// JavaScript example using toLocaleString()
const price = 1234.56;
const formatted_price = price.toLocaleString('nl-NL', {
style: 'currency',
currency: 'EUR'
});
console.log(formatted_price); // Output: € 1.234,56
// Incorrect Currency Formatting (US style)
const price = 1234.56;
const formatted_price = price.toLocaleString('en-US', {
style: 'currency',
currency: 'EUR'
});
console.log(formatted_price); // Output: €1,234.56 (Incorrect for Dutch users)
Handling Percentages
Percentages are generally written with a space between the number and the percentage sign (%). For example, 25 % (note the space). Example 5: Correct Percentage Formatting// Python example
percentage = 25
formatted_percentage = str(percentage) + " %"
print(formatted_percentage) # Output: 25 %
Translation and Terminology
Accurate and consistent translation is paramount for user comprehension. This section focuses on the importance of choosing appropriate terminology and maintaining consistency throughout the application’s Dutch translation.Choosing the Right Terminology
Selecting the correct Dutch terms is critical to avoid confusion and ensure clarity. Avoid literal translations, which can often sound awkward or unnatural. Instead, focus on conveying the intended meaning in a way that is natural and idiomatic for Dutch speakers. Consider the context in which the term is used. A word may have multiple meanings, so choose the meaning that is most appropriate for the specific situation. Example 1: Context-Aware Translation| English Term | Incorrect Translation (Literal) | Correct Translation (Contextual) | Explanation |
|---|---|---|---|
| “Save” (a file) | “Redden” | “Opslaan” | “Redden” means “to rescue,” while “Opslaan” correctly means “to save” a file. |
| “Run” (a program) | “Rennen” | “Uitvoeren” | “Rennen” means “to run” in the sense of physical running, while “Uitvoeren” means “to execute” or “run” a program. |
- “User Interface” should be translated to “Gebruikersinterface”, not a literal translation.
- “Password” should be translated to “Wachtwoord”.
- “Settings” should be translated to “Instellingen”.
Maintaining Consistency
Consistency is key to a professional and user-friendly experience. Once a term has been translated, use the same translation consistently throughout the entire application. Inconsistency can lead to confusion and frustration. Create a glossary of terms to ensure consistency across all translations. Example 3: Consistent Terminology If you translate “Edit” as “Bewerken” in one part of the application, use “Bewerken” consistently for “Edit” throughout the entire application, not “Wijzigen” or another synonym. Example 4: Using a Translation Memory System (TMS) Implementing a TMS helps maintain consistency by storing previously translated segments and suggesting them for reuse in similar contexts. This not only saves time but also ensures that terminology is used consistently.Avoiding Ambiguity
Some English terms can be ambiguous and have multiple meanings. In such cases, carefully consider the context and choose the Dutch translation that best reflects the intended meaning. If necessary, rephrase the English text to remove the ambiguity before translating it. Example 5: Resolving Ambiguity| English Term | Possible Meanings | Dutch Translation (Context Dependent) |
|---|---|---|
| “Report” | A document; To inform | “Rapport” (document); “Rapporteren” (to inform) |
| “Address” | A location; To speak to | “Adres” (location); “Toespreken” (to speak to) |
Cultural Considerations in Text and UI
Beyond accurate translation, understanding Dutch cultural nuances is vital. This section addresses aspects of the user interface and text that require careful attention to resonate with Dutch users effectively.Tone and Formality
The Dutch language has both formal and informal forms of address. In general, it’s best to err on the side of formality, especially in professional contexts, unless you know your audience well. Using the formal “u” instead of the informal “je” or “jij” is generally recommended in business settings and when addressing users you don’t know personally. Example 1: Formal vs. Informal Address| Context | Informal (“je/jij”) | Formal (“u”) |
|---|---|---|
| Greeting a user in a banking application | “Welkom, je saldo is…” | “Welkom, uw saldo is…” |
| Asking for confirmation in a registration form | “Ben je zeker?” | “Bent u zeker?” |
Color and Imagery
While color preferences are subjective, certain colors have cultural associations. Orange is strongly associated with the Netherlands due to the House of Orange-Nassau, the Dutch royal family. While using orange can be a good way to connect with Dutch users, avoid overusing it, as it can be overwhelming. Be mindful of using colors associated with rival sports teams (e.g., avoiding red and white when targeting supporters of specific football clubs.) Example 3: Appropriate Use of Orange Using orange sparingly in a logo or as an accent color can be effective. Using it as the primary color for the entire user interface might be overwhelming. Example 4: Image Selection Choose images that are relevant to the Dutch culture. For example, images of windmills, tulips, or bicycles can resonate with Dutch users. However, avoid stereotypes and ensure the images are authentic and respectful. Also, ensure that images depict a diverse representation of the Dutch population.Layout and Whitespace
Dutch users generally appreciate clean and well-organized layouts. Using sufficient whitespace can improve readability and prevent the interface from feeling cluttered. Be mindful of the fact that Dutch text tends to be longer than English text, so ensure that your layout can accommodate longer strings of text without breaking. Example 5: Adapting Layout for Dutch Text When translating button labels or menu items from English to Dutch, ensure that the buttons and menus are wide enough to accommodate the longer Dutch text. If necessary, adjust the layout to allow for more space. For example, “Submit” might become “Verzenden,” which requires more horizontal space. Example 6: Prioritizing Information Dutch users generally prefer direct and concise communication. Prioritize the most important information and present it clearly and prominently. Avoid unnecessary jargon or fluff.

Ensuring accessibility is not only ethically important but also legally required in many regions. This section focuses on key accessibility considerations for Dutch-speaking users to ensure that your application is usable by everyone, including those with disabilities. While not specifically mandated by “Guidelines Nederlands” directly, accessibility is indirectly important for inclusive implementation of software for the Dutch market.Web Content Accessibility Guidelines (WCAG)
The Web Content Accessibility Guidelines (WCAG) are an internationally recognized standard for web accessibility. Adhering to WCAG principles is essential for creating accessible websites and applications. WCAG covers a wide range of accessibility issues, including visual, auditory, motor, and cognitive impairments. Aim for at least WCAG 2.1 Level AA compliance. Example 1: Implementing ARIA Attributes Use ARIA (Accessible Rich Internet Applications) attributes to provide semantic information about UI elements to assistive technologies like screen readers.<button aria-label="Verzenden">Verzenden</button>
<img src="logo.png" alt="Bedrijfslogo">
Keyboard Navigation
Ensure that all interactive elements can be accessed and operated using the keyboard. This is essential for users who cannot use a mouse or other pointing device. Example 3: Ensuring Tab Order The tab order should follow the logical flow of the user interface. Use the `tabindex` attribute to control the tab order if necessary. Avoid using `tabindex` unnecessarily, as it can disrupt the natural tab order. Example 4: Providing Focus Indicators Provide clear and visible focus indicators for keyboard users. The focus indicator should clearly highlight the currently focused element./* CSS to style the focus indicator */
:focus {
outline: 2px solid blue;
}
Color Contrast
Ensure that there is sufficient color contrast between text and background colors. Insufficient contrast can make it difficult for users with low vision to read the text. WCAG requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Example 5: Checking Color Contrast Use a color contrast checker tool to verify that the color contrast meets WCAG requirements. There are many free online tools available. Example 6: Providing Alternative Text Styles Allow users to customize the text size, font, and color scheme to meet their individual needs. This can be achieved by providing user-configurable settings or by using assistive technologies. By adhering to these accessibility guidelines, you can ensure that your application is usable by a wider audience, including Dutch-speaking users with disabilities.
