Key takeaways
- Text features are the parts of a nonfiction text—headings, captions, diagrams, bold words and more—that sit outside the main paragraphs and help readers find, understand and remember information.
- They fall into two broad groups: print/organizational features (headings, index, glossary) and graphic/visual features (photos, diagrams, maps, charts).
- Authors add features for three reasons: to organize information, to explain it visually, and to emphasize what matters most.
- Text features are not the same as text structure—features are the visible tools on the page; structure is how the ideas are arranged (cause/effect, compare/contrast, sequence).
- The fastest way to teach them is a 'text feature walk': previewing every feature before reading the body text.
Open any nonfiction book, science article or textbook chapter and you'll see more than paragraphs. You'll see bold keywords, a heading at the top of each section, a photo with a caption, maybe a labeled diagram or a map. Those extras are text features—the navigational and visual tools an author adds so a reader can locate information quickly and understand it deeply.
Strong readers use text features before, during and after reading: they skim headings to predict, check a diagram to make sense of a hard paragraph, and use the index to find a fact fast. Weaker readers often skip straight to the paragraphs and miss half the page. Teaching features explicitly closes that gap, and it's a skill every state's reading standards expect students to master by upper elementary.
A useful way to explain features to students is the three-purpose rule: every feature exists to organize information (so you can find it), to illustrate information (so you can picture it), or to emphasize information (so you don't miss it). If a student can name the purpose of a feature, they're reading it the way the author intended.
Print and organizational text features
These features are made of words and page layout. Their job is to organize the text and help readers navigate—jumping to the right section without reading front to back.
Headings & subheadings
Bold labels that name each section. Readers skim them to preview a text and to jump to the part they need—like 'How Volcanoes Form.'
Table of contents
A front-of-book list of chapters or sections with page numbers, used to locate a topic before you start reading.
Index
An alphabetical list of topics and page numbers at the back of a book—the fastest way to find one specific fact.
Glossary
A mini-dictionary of the book's key terms and their definitions, usually near the back. Great for domain vocabulary.
Bold & highlighted words
Keywords printed in bold or color to signal 'this word is important'—often the same terms defined in the glossary.
Captions
A short line of text under a photo or illustration that explains what you're looking at and why it matters.
Labels
Words that point to specific parts of a diagram or photo, such as naming the 'stem,' 'petal' and 'root' on a plant.
Sidebars & text boxes
Boxed-off text set apart from the main column, holding a 'Did you know?' fact, a definition or a related mini-topic.
Graphic and visual text features
These features carry information through images and data rather than sentences. They let an author show something that would take a paragraph to describe—and they're often where the hardest, most testable information lives.
Photographs & illustrations
Real photos or drawings that show what a topic actually looks like—paired with a caption to anchor the meaning.
Diagrams
Simplified drawings with labels that explain how something works or is built, like the water cycle or parts of a cell.
Maps
Show where events, places or features are located, often with a key/legend and compass rose to read them.
Charts & graphs
Bar graphs, line graphs and pie charts that turn numbers into a picture so readers can compare data at a glance.
Tables
Rows and columns that organize facts for easy comparison—like average rainfall by month across several cities.
Timelines
A dated line showing the order events happened in, used to see sequence and how much time passed between events.
Text features vs. text structure
Students (and quiz questions) mix these up constantly. Text features are the visible tools on the page. Text structure is the invisible way the author arranges the ideas. A single article can use many features while following one main structure.
| Question | Text features | Text structure |
|---|---|---|
| What is it? | The visible parts around the main text (headings, captions, diagrams) | How the ideas are organized inside the text |
| Can you see it? | Yes—you can point to it on the page | No—you infer it from how the writing flows |
| Examples | Bold words, index, glossary, maps, sidebars | Cause & effect, compare & contrast, sequence, problem & solution |
| Reader's question | 'Where do I look for this information?' | 'How is the author connecting these ideas?' |
How to teach text features (5 steps that work)
- 1
Start with a text feature walk
Before reading a nonfiction page, have students preview only the features—headings, images, captions, bold words—and predict what the text will be about. This mirrors how skilled readers actually approach nonfiction.
- 2
Build an anchor chart together
Co-create a class chart listing each feature, a quick sketch, and its purpose (organize, illustrate or emphasize). Keep it visible and add to it as new features appear in reading.
- 3
Run a scavenger hunt
Give pairs a magazine, a nonfiction book or a printed article and a checklist. Students hunt for and tag each feature, then explain what information it added. This turns a definition into a skill.
- 4
Ask 'why did the author include this?'
For every feature, push past naming it to its purpose. A caption on a photo of erosion isn't decoration—it tells you which coastline and over how many years. Purpose is where comprehension happens.
- 5
Have students create their own
Ask students to write a short nonfiction page on a topic they know and add at least four features—a heading, a labeled diagram, a bold key term and a caption. Making features cements how they work.
Once students can name and use features, give them repeated practice on fresh texts. Short, focused worksheets—label the diagram, match the feature to its purpose, use the index to find a page—turn recognition into an automatic reading habit. Rotate the nonfiction topics (animals, weather, history, sports) so students transfer the skill instead of memorizing one passage.

Text features are the parts of a nonfiction text that aren't the main paragraphs—things like headings, bold words, captions, diagrams, maps, a glossary and an index. They help readers find information quickly and understand it more deeply.
Print/organizational features (headings, table of contents, index, glossary, bold words) that help you navigate the text, and graphic/visual features (photos, diagrams, maps, charts, tables, timelines) that show information as images or data.
Text features are the visible tools on the page you can point to. Text structure is how the author organizes the ideas—such as cause and effect, compare and contrast, sequence, or problem and solution. One article uses many features but usually one main structure.
Most students are introduced to basic features like titles, headings and pictures in kindergarten through 2nd grade, and are expected to use features such as the glossary, index, captions and diagrams to locate and interpret information by 3rd–5th grade.
