Hand and finger load
- Synchronized data appears here after analysis.
Analysis shows the load assigned to both hands and all eight fingers.
Keyboard Layout Analyzer
Enter Latin text or recorded key sequences to compare QWERTY, Dvorak, and Colemak by key frequency, finger load, and adjacent-key patterns.
Input and analysis settings
43 / 20000
Up to 20,000 characters. Chinese characters do not reveal the actual input-method key sequence; use pinyin, Latin text, or recorded keys.

The table compares like-for-like measures; it does not rank a single best layout. Learning cost, personal fingering, and real speed are outside this model.
More information
Method, formulas, and result meaning
Characters are normalized with NFKC, lowercased, and mapped to the selected layout's fixed 30-key letter area. Same-finger rate = consecutive pairs assigned to one finger ÷ all consecutive valid pairs; hand alternation uses the same denominator. Finger load = that finger's keys ÷ valid keys. Movement is an estimated Euclidean distance between key centers in model units.
Spaces, line breaks, and unsupported characters break adjacent pairs, so the ends of separate words or unknown segments are not connected.
Counts and distances remain unrounded internally. Percentages show one decimal place and average movement shows two; comparisons use the original values.
Scope and limitations
Only fixed QWERTY, Dvorak, and Colemak 30-key letter areas and standard fingering are modeled. Chinese characters may come from different input methods and cannot reveal a unique key sequence. Shift layers, shortcuts, spaces, Enter, and custom fingering are outside the model.
What does same-finger rate mean?
It is the share of adjacent valid key pairs assigned to the same finger. A higher value only describes this fixed model; it is not a direct speed or comfort result.
Why does the analyzer not choose the best layout?
Metrics can conflict, and language, fingering, shortcuts, and learning cost differ. The page reports separate measures instead of inventing an absolute ranking.
How are spaces and unsupported characters handled?
They are excluded from the 30-key counts and break adjacent pairs, so characters on opposite sides are not treated as consecutive keys.
Tool information and sources
Text and analysis results stay in this browser. Nothing is uploaded, no remote API is called, the URL is not written, and local storage is not used.
The tool uses no third-party runtime code or assets; the layout maps, algorithm, and interface are independently implemented.
