How to Use a Schulte Table

Choose a readable grid, find targets in order, and use time and errors for personal, like-for-like review.

Six steps

1
Choose a grid
Start with a size whose targets are clear on your screen. Smaller grids create shorter tasks.
2
Set a comfortable view
Adjust screen distance, text size, contrast, and input method. You do not need to hold your eyes completely still.
3
Start the round
Select Start, wait for the layout, and locate the first target.
4
Follow the sequence
Select each next number in ascending order. An incorrect selection adds to the error count.
5
Finish accurately
Continue through the final target. Pause if the grid becomes tiring or uncomfortable.
6
Review the result
Read completion time together with errors and compare only attempts using the same size and setup.

You may keep your gaze near the center as a visual-search cue, but move your eyes whenever needed for clear, comfortable viewing.

A lower time with more errors is not a like-for-like better result.

There is no site-defined ideal duration or frequency. A short round may be easier to repeat than a long session.

Do not compare total times across different grid sizes.

No. A central gaze is an optional cue. Move your eyes as needed for clear and comfortable viewing.

Choose a duration that remains comfortable. Stop when accuracy drops or you experience eye, head, or hand discomfort.

There is no required number. One accurate round can be enough.

Compare time and errors from attempts using the same grid, device, input method, and rules.
