Schulte table — online attention trainer

The classic attention trainer: find all the numbers in order as fast as you can. The Schulte table trains concentration, visual search speed and peripheral vision — right in the browser, free and with no sign-up.

Grid size

Tap the numbers in order — from 1 to the last — as fast as you can. Keep your gaze on the centre and find numbers with your peripheral vision.

Time norms for the 5×5 table

Reference points for adults on the classic 5×5 table (25 numbers). This is a practice scale, not diagnostics: fatigue, sleep and experience all affect the time. For 4×4 and 3×3 the trainer scales the thresholds proportionally.

  • under 25 sExcellent — attention is fast and stable
  • 26–35 sGood result — faster than typical
  • 36–45 sTypical range for adults
  • 46–60 sSlower than typical — possibly fatigue or lost focus
  • over 60 sNotably slower than the reference — mind your sleep, stress and deficiencies

What a Schulte table is

A Schulte table is a square grid with numbers scattered at random; the task is to find them in order in the shortest possible time. The method was introduced by German psychiatrist Walter Schulte, and psychologists have used it ever since to assess attention stability and visual search speed, while speed-reading coaches use it to widen the visual field.

The point is not speed alone. Regular practice teaches you to hold your gaze on the centre and “grasp” the surrounding numbers with peripheral vision — a skill that transfers to reading, driving and any work where noticing details quickly matters.

How to do it properly

The classic method differs from simply “click faster”. For the exercise to actually train attention and peripheral vision:

  • keep your gaze on the centre of the grid and find numbers with your side vision instead of scanning row by row;
  • don’t say the numbers to yourself — inner speech slows the search down;
  • practise a little but regularly: 2–4 tables a day beats a long weekly marathon;
  • for honest progress tracking, practise at the same time of day — attention depletes by the evening.

What affects your result

Completion time is not a constant: for the same person it visibly drifts through the day. Sleep deprivation, fatigue, stress and monotonous screen work before the exercise make it worse; rest, movement and practice make it better.

If attention and processing speed stay low for weeks, the cause can be physical: iron (ferritin) or vitamin B12 deficiency, an underactive thyroid, poor sleep. These show up in ordinary lab tests — worth checking before blaming “bad concentration”.

Schulte tables and speed reading

In speed reading, Schulte tables are a foundational drill. Reading speed is limited by the number of eye fixations per line: the wider the field you grasp in one fixation, the fewer stops your eyes need. Regular table practice widens this field, and text starts to read in large blocks rather than word by word.

Frequently asked questions

  • For adults on the classic 5×5 table the typical range is about 36–45 seconds; under 35 seconds is a good result, and under 25 seconds is excellent. Over a minute usually points to fatigue or lost focus rather than “bad attention” — retry when rested.

  • Ideally 2–4 tables a day, regularly. Consistency is what works: short daily sessions train attention better than rare long ones. The first noticeable gains usually come in 2–3 weeks.

  • Yes, it is a classic attention exercise for school-age kids. Children usually get smaller grids — 3×3 and 4×4 — and take longer than adults. Our norms are for adults, so for a child track their own progress rather than the scale.

  • That’s normal. Attention is a resource that depletes through the day: after work, screens and stress the search slows down. For a fair comparison, practise at the same time of day.

  • No. The online table is a trainer and a reference point, not a medical test. A clinical assessment of attention is done by a professional. If distractibility interferes with your life, start with the adult ADHD screener and discuss the result with a doctor.

  • If your time stays well above the reference for weeks and you feel constant fatigue or “brain fog”, check the physical causes: ferritin and iron, vitamin B12, TSH (thyroid), sleep quality. Upload your lab results to our service — AI explains every value.
