Technical product catalogs call for clean design, the right information hierarchy and easy-to-read tables. When product features, application areas and comparison data are structured well, a catalog becomes a powerful tool for the sales team. In this article on technical catalog design, we explain how to plan the content, how to lay out a product page and how to make tables and drawings easy to read.
In short
- A technical catalog helps readers find and compare the right product quickly; decoration comes second.
- First, collect product families, the code system and the information each page will hold in one inventory.
- Use the same template on every product page, so readers find information in the same place every time.
- In tables, put a readable product name or code in the first column and state units once in the header.
- Prepare technical drawings as vectors, with consistent line weights and dimension style.
Who is a technical catalog for?
The reader of a technical catalog is usually in a hurry and knows what they are looking for. A purchasing specialist looks for a product of a specific size. An engineer compares pressure, capacity or material values. A sales representative, meanwhile, wants to open the right page in a few seconds in front of a customer.
That is why the first question in technical catalog design should not be "how will it look nice?" but "how quickly will readers find what they need?" User experience (UX) principles apply here too; we cover them in our article what is UX design.
A well-planned visual foundation makes a brand look more professional. Giving users quick access to the information they need also has a direct impact on sales, whether the catalog is printed or digital.
1. Start with a content inventory
Before you move on to design, organize the information you have. A simple spreadsheet is enough. Write one product per row and one information field per column: product name, code, short description, applications, technical values, options, and photo and drawing status.
This inventory shows you three things. First, you see which information is missing. Second, it becomes clear how to group products into families. Finally, you decide which fields will be fixed on every product page. Keeping the data in a single source also reduces the risk of errors when you update the catalog.
2. Build the information hierarchy at catalog level
When readers open the catalog, they should understand its overall structure first. For this, you can use the following tools:
- Table of contents: A simple list showing product families and page numbers.
- Section colors or tabs: Giving each product family a small colored strip on the page edge makes it easier to find a section in a printed catalog.
- Section opening pages: A short description of the family, its common applications and a summary comparison of the products in it.
- Index: A list sorted by product code is very useful, especially for buyers who search by code.
3. Product page layout: the same template on every page
The most important rule of technical catalog design is consistency. Once readers learn one product page, they should be able to read all the others. For this reason, use the same grid and the same order on every product page. A sample order might look like this:
- Product name and product code
- A one- or two-sentence description of the benefit
- Product photo or 3D view
- Applications (can be supported with icons)
- Technical data table
- Technical drawing and dimensions
- Options, accessories and order codes
That way, someone looking for a product's pressure rating looks in the same place on every page. Also, don't be afraid of white space; cramped pages tire technical readers too.
4. How to prepare readable tables
Tables are the heart of a technical catalog. The principles Nielsen Norman Group recommends for data tables are a good guide for printed tables as well:
- Make the first column an identifier. Put a meaningful product name or code in the first column so readers can find the row they need.
- Order columns by importance. Bring the most-compared values forward and keep related columns next to each other.
- Keep headers visible. If a table runs across several pages, repeat the header row on each page.
- Help the eye track. Thin rules or light-toned row stripes (zebra striping) keep readers from losing their row.
Units and number formatting
Instead of repeating units in every cell, state them once in the column header; for example, "Flow rate (L/h)". Under the International System of Units (SI), a space separates the number from the unit symbol: "25 °C", "10 bar", "51 mm × 51 mm". Angle units such as degrees, minutes and seconds, however, are written without a space: "30°". Also align numbers on the decimal marker. As a result, readers can compare values at a glance.
In addition, tie the decimal separator and unit style to a single rule throughout the catalog. If you use a comma in the Turkish catalog and a point in the English one, apply that the same way in every table.
5. Technical drawings and product images
Technical drawings explain a product's dimensions and structure faster than words. The ISO 128 standard sets out general principles of presentation for views, sections and line types in technical drawings. Following the same logic in catalog drawings helps engineers read them easily.
Prepare drawings in vector format. Vector drawings stay sharp at any size, and thin lines don't disappear in print. We explain this difference in detail in our article on vector vs. raster images. Beyond that, use the same line weights, the same dimension arrows and the same typeface throughout the catalog.
Consistency matters in product photos too. The same background, the same lighting direction and similar angles make the catalog look as if it came from a single hand. If photos are lacking, or if you need to show the product's internal structure, technical illustration is a good alternative.
6. Plan print and digital catalogs together
Today, technical catalogs are often printed and also shared as PDFs. That is why you should plan both uses together from the start:
- For the printed catalog: Follow the printer's specification for bleed, color profile and PDF. You can find the details in our article on packaging design prepress; the same rules apply to catalogs.
- For the digital PDF: Make the table of contents and page headings clickable, and keep the text selectable and searchable. Keep the file size small enough to send by email.
- Version tracking: Put the catalog version and date on the front or back cover. That way, the sales team won't quote from an old catalog.
Technical catalog design checklist
| Check | Question |
|---|---|
| Content inventory | Is all product information collected in one table? |
| Catalog structure | Are there a table of contents, section colors and a code index? |
| Product page | Do all pages use the same template and order? |
| Tables | Is the first column an identifier, are units in the header, are headers repeated? |
| Drawings | Are they vectors with consistent line and dimension style? |
| Digital PDF | Do links work, and is the text searchable? |
| Version | Does the cover show the version and date? |
Our experience
In catalog projects, we discuss content and use cases before design. In our projects, we follow this approach:
- We start with an analysis of your goals, sector and competitors, and look at how competing catalogs present information.
- We plan page structure and content flow around the reader's intent, that is, the information they are looking for.
- We build the design language to strengthen brand perception, in line with the corporate identity.
- We set up the technical foundation with a focus on speed and manageability, organizing product data in updatable templates.
- After launch, we use feedback from the sales team to note improvements for the next version.
Thanks to our illustration and technical drawing service, we also prepare product drawings and section views within the same team. As a result, the drawings and the page design speak the same visual language.
Frequently asked questions
How much text should a technical catalog have?
Little, but clear. Technical readers look for values, tables and drawings rather than long paragraphs. For each product, a one- or two-sentence benefit description and its applications are usually enough.
Printed catalog or digital catalog?
For most businesses, both. A printed catalog is useful at trade fairs and in face-to-face meetings. A digital PDF, on the other hand, is quick to share by email and easy to update. Designing for both uses from the start is the most efficient approach.
What should I do if my product range changes often?
Build the catalog in modules. If product families are separate sections, you can update only the section that changes. In addition, keeping product data in a single table reduces the risk of errors during updates.
Conclusion
Catalog design for technical products should help readers find and compare the right product quickly. When a clean layout, a consistent product template, readable tables and clear technical drawings come together, the catalog becomes a tool the sales team uses every day. Successful work comes from thinking about design and technical knowledge together. Artsution considers not only what a brand needs today, but also the foundation it will need as it grows.
