Basic flowchart symbols

Common Flowchart Symbols

Flowcharts use special shapes to represent different types of actions or steps in a process. Lines and arrows show the sequence of the steps, and the relationships among them. These are known as flowchart symbols.

What Shapes Are Used in Flowcharts

Flowcharts consist of a few common geometric shapes representing steps. The most common shape is a rectangle used to show a single action or operation.

What are the Basic Symbols of a Flowchart?

Let's go over each flowchart symbol individually.

Start and End Symbol

Start/End Symbol

The terminator symbol marks the starting or ending point of the system. It usually contains the word "Start" or "End."

Action or Process Symbol

Action or Process Symbol

A box can represent a single step ("add two cups of flour"), or an entire sub-process ("make bread") within a larger process.

Document Symbol

Document Symbol

A printed document or report.

Multipe Documents Symbol

Multiple Documents Symbol

Represents multiple documents in the process

Decision Symbol

Decision Symbol

A decision or branching point. Lines representing different decisions emerge from different points of the diamond.

Input/Output Symbol

Input/Output Symbol

Represents material or information entering or leaving the system, such as customer order (input) or a product (output).

Manual Input Symbol

Manual Input Symbol

Represents a step where a user is prompted to enter information manually.

Preparation Symbol

Preparation Symbol

Represents a set-up to another step in the process.

Connector Symbol

Connector Symbol

Indicates that the flow continues where a matching symbol (containing the same letter) has been placed.

Or Symbol

Or Symbol

Indicates that the process flow continues in more than two branches.

Summoning Junction Symbol

Summoning Junction Symbol

Indicates a point in the flowchart where multiple branches converge back into a single process.

Merge Symbol

Merge Symbol

Indicates a step where two or more sub-lists or sub-processes become one.

Collate Symbol

Collate Symbol

Indicates a step that orders information into a standard format.

Sort Symbol

Sort Symbol

Indicates a step that organizes a list of items into a sequence or sets based on some pre-determined criteria.

Subroutine Symbol

Subroutine Symbol

Indicates a sequence of actions that perform a specific task embedded within a larger process. This sequence of actions could be described in more detail on a separate flowchart.

Manual Loop Symbol

Manual Loop Symbol

Indicates a sequence of commands that will continue to repeat until stopped manually.

Loop Limit Symbol

Loop Limit Symbol

Indicates the point at which a loop should stop.

Delay Symbol

Delay Symbol

Indicates a delay in the process.

Data Storage or Stored Data Symbol

Data Storage or Stored Data Symbol

Indicates a step where data gets stored.

Database Symbol

Database Symbol

Indicates a list of information with a standard structure that allows for searching and sorting.

Internal Storage Symbol

Internal Storage Symbol

Indicates that information was stored in memory during a program, used in software design flowcharts.

Display Symbol

Display Symbol

Indicates a step that displays information.

Off Page

Off Page

Indicates that the process continues off page.

Frequently Asked Questions (FAQ) About Flowchart Symbols

What does a parallelogram flowchart symbol mean?

A parallelogram represents data in a flowchart. Data is either input a process requires or an output that the proces hands off to the next step.

What are the types of flowcharts?

The most common flowchart types are:

  • Process flowchart
  • Swimlane Flowchart
  • Workflow Diagram
  • Data Flow Diagram
  • EPC Diagram

What is input and output in a flowchart?

Input and output are the fundamental building blocks of a process used to describe a software program. For example, the input could be provided by a user like at an ATM machine or in a form online or it could data provided by an instrument like a temperature read. The program will have code to interpret the input and generate an output. The output could be a series of things: a message printed on a the user interface or data handed off to another process.

Input/Output Flow
What are the symbols used in Data Flow Diagrams (DFD)?

There are two different types of approaches to symbols in data flow diagrams: Yourdon and Coad and Gane and Sarson.

In the Yourdon and Coad way, processes are depicted as circles, while in the Gane and Sarson diagram the processes are squares with rounded corners.

Quick Tips for Using Flowchart Symbols

Most of the flowchart symbols shown here are for use in very specific applications, such as a data flow diagram used for computer programming. Unless you have specialized knowledge and your diagram is being developed for a peer group with similar knowledge, it's best to stick to basic flowchart symbols. If more than the most basic flowchart symbols appear in your diagram, it is good practice to include a legend or symbol key.

Most flowcharts should be built using only the Start/End and Action or Process symbols and should follow a very basic set of best practices. Sticking with these two primary flowchart symbols is the best way to ensure that your diagram will be easy to understand.
