What is a Schulte Table?
A complete guide to the Schulte Table — its history, how it works, the science behind it, and why millions use it for brain training.
Definition
A Schulte Table is a square grid filled with randomly arranged numbers, letters, or colors. The fundamental task is simple: find and click (or point to) each item in a specific sequence — typically ascending numerical order — as quickly as possible.
The key principle that makes Schulte Tables effective is the technique required to complete them efficiently: rather than scanning the grid systematically, the practitioner must keep their gaze fixed at the center of the grid and use peripheral vision to locate each target. This trains the brain to process a wider visual field simultaneously.
History and Origin
The Schulte Table was developed by German psychologist Walter Schulte in the 1950s. Schulte was researching methods to assess and improve attention and visual processing in clinical patients. He designed the numbered grid as a standardized tool for measuring visual scanning speed and attention quality.
The tool gained widespread adoption in the Soviet Union and Eastern Europe during the 1960s–1980s, where it was used extensively in sports psychology, military training, and educational programs. Soviet athletes and cosmonauts used Schulte Tables as part of their cognitive conditioning regimens.
In the 1990s and 2000s, Schulte Tables became a staple of speed reading programs worldwide. Speed reading instructors recognized that the peripheral vision training provided by Schulte Tables directly improved reading speed by reducing the number of eye fixations per line.
Today, Schulte Tables are used globally in education, sports training, cognitive rehabilitation, and personal development. Digital versions have made them accessible to anyone with a smartphone or computer.
How Schulte Tables Work
The effectiveness of Schulte Tables comes from the cognitive demands they place on the visual system. When you attempt to complete a Schulte Table efficiently, your brain must:
- •Maintain a stable central fixation point (center of the grid)
- •Process visual information from the peripheral visual field
- •Identify target numbers among distractors
- •Execute rapid motor responses (clicking/pointing)
- •Track which numbers have been found (working memory)
- •Maintain sustained attention throughout the task
Regular practice strengthens all of these cognitive functions simultaneously, producing improvements that transfer to real-world tasks like reading, driving, sports, and any activity requiring rapid visual processing.
Grid Sizes and Difficulty
Schulte Tables come in various sizes, each offering a different level of challenge:
3×3 (9 numbers)
Beginner level. Perfect for children and first-time users.
4×4 (16 numbers)
Easy level. Good stepping stone to the standard 5×5.
5×5 (25 numbers)
Standard level. The most widely used size for training.
6×6 (36 numbers)
Intermediate level. Significantly more challenging than 5×5.
9×9 (81 numbers)
Advanced level. For serious practitioners only.
10×10 (100 numbers)
Expert level. The ultimate Schulte Table challenge.

Frequently Asked Questions
What is a Schulte Table?
A Schulte Table is a square grid filled with randomly arranged numbers (or letters/colors). The task is to find and click each number in ascending order as quickly as possible, training peripheral vision and cognitive speed.
Who invented the Schulte Table?
The Schulte Table was developed by German psychologist Walter Schulte in the 1950s. He originally used it as a clinical tool to assess and train attention and visual processing in patients.
What size is a standard Schulte Table?
The standard Schulte Table is 5×5, containing 25 numbers. However, sizes range from 3×3 (beginner) to 10×10 (expert), and some practitioners use even larger custom grids.
How does a Schulte Table work?
Numbers are randomly arranged in a grid. You must find and click them in ascending order (1, 2, 3…) as fast as possible. The key technique is keeping your gaze at the center and using peripheral vision to locate numbers.
Is Schulte Table training scientifically proven?
Yes. Multiple studies have demonstrated that Schulte Table training improves peripheral vision, reading speed, and attention. It is used in clinical settings, sports training, and educational programs worldwide.
