What are the best practices for designing tables that are easy to read? (2024)

The first step to designing a table that is easy to read is to choose the right format for your data. Depending on the type and purpose of your data, you may want to use a different format, such as a text table, a matrix table, or a summary table. A text table is a simple table that shows text or numbers in rows and columns, without any calculations or aggregations. A matrix table is a table that shows the relationship between two or more variables, such as a cross-tabulation or a correlation matrix. A summary table is a table that shows the results of some calculations or aggregations on the data, such as a mean, a median, or a percentage.

When designing a table that is easy to read, the second step is to use a clear layout that organizes your data and highlights the most important information. To achieve this, you can use white space to separate different sections of your table, such as the header, the body, and the footer. Additionally, align your data horizontally and vertically, and maintain consistent spacing and indentation. Furthermore, use grid lines sparingly, and avoid using vertical lines unless necessary. To help identify your data, you can use row and column labels; however, if you do use abbreviations or symbols, be sure they are well-known or explained. Lastly, you can sort, group or filter your data in a logical order and use subtotals or totals to summarize it.

The third step to designing a table that is easy to read is to choose the right color for your data and your background. Color can be a powerful tool to emphasize or differentiate your data, or to convey meaning and create contrast, however it can also be distracting, confusing, or misleading if not used correctly. When selecting colors for your table, use them sparingly and only to emphasize or differentiate your data; opt for a neutral or light background color and a darker or brighter color for your data; stick to a consistent color scheme throughout the table; use color to show categories, patterns, or trends in your data but avoid using it to show exact values or comparisons; and be mindful of the cultural or emotional associations of some colors when using it to show positive or negative values.

When designing a table that is easy to read, choosing the right font is an important fourth step. Font can affect the readability, legibility, and professionalism of your table, so it’s best to select a font that is appropriate for your audience, topic, and medium. Sans-serif fonts are best for text, while serif or monospaced fonts are better for numbers. Additionally, use a standard or common font that is compatible with different devices and platforms, and make sure the font size is large enough to read but not too large to fit your table in the slide or page. Emphasize or differentiate your text with bold, italic, or underline, but avoid overusing them or mixing them. Finally, use upper and lower case letters instead of all caps or all lowercase letters as they are harder to read and scan.

When designing a table, it's important to avoid certain pitfalls and mistakes that can make it confusing or misleading. These include using too much or too little data, not showing the source, date, or units of your data, not using commas, periods, or spaces to separate numbers, using ambiguous or inconsistent terms, labels, or abbreviations without defining them, and using misleading or inappropriate scales, ranges, or axes. Additionally, avoid 3D effects, shadows, or gradients; instead opt for simple and flat designs that are easier to read and interpret.

The sixth and final step to designing a table that is easy to read is to test your table with your audience and yourself. Testing your table can help you identify and fix any errors, gaps, or inconsistencies in your data, format, layout, color, or font. To do this, you can ask someone from your target audience to look at your table and provide feedback on its clarity, accuracy, and relevance. Additionally, ask yourself questions about the main message or purpose of the table, its key points or takeaways, how it supports or complements the presentation, and how it compares or contrasts with other tables or charts in the presentation. Lastly, review your table for any spelling, grammar, or punctuation mistakes and check your data for any errors or outliers.
