A keyboard layout analyzer measures how efficiently you type a given text on different layouts. Paste your typical text — code, prose, emails — and compare QWERTY, Dvorak, Colemak, Colemak-DH, and Workman across finger travel distance, hand alternation, home row usage, and same-finger bigrams.

How to Use the Keyboard Layout Analyzer
The keyboard layout analyzer helps you make an informed decision about whether switching layouts makes sense for your specific typing habits. Different text types — code, prose, data entry — favor different layouts. Analyzing your actual text gives a more accurate picture than generic English frequency data.
Step 1: Enter a Representative Text Sample
Paste a sample of text you actually type — a few paragraphs of code, an email thread, a document excerpt. Use the preset buttons to load common text types. The longer the sample, the more accurate the statistical analysis. Aim for at least 200 characters for meaningful results; 1000+ characters gives highly accurate data.
Step 2: Select Layouts to Compare
Choose which layouts to include in the analysis. QWERTY, Dvorak, and Colemak are selected by default. Enable Colemak-DH if you use or are considering an ergonomic board. Workman is a less common but well-regarded alternative optimized for lateral finger movement. You can compare up to all five simultaneously.
Understanding the Metrics
Finger travel estimates the total key-to-key distance in normalized units. Lower is better — less movement means less effort and strain. Home row usage measures what percentage of keystrokes land on the middle row. Higher is better — you want your fingers to stay near the home position. Hand alternation measures how often keystrokes alternate between hands. Moderate to high alternation (50–70%) is generally considered good. Same-finger bigrams (SFB) are consecutive keys typed with the same finger. Lower is better — high SFB forces awkward finger repositioning that slows you down and increases strain.
What the Score Means
The overall score combines all four metrics into a single efficiency number relative to the other layouts in your comparison. A score of 100 means the best performer for your specific text. The score is not an absolute measure of layout quality — it is a relative ranking for your sample text. The same layout may score differently on code versus prose.
FAQ
Is this keyboard layout analyzer free?
Yes, completely free with no signup required. All analysis runs locally in your browser — your text is never sent to any server.
Is my text private when using this tool?
Absolutely. Everything runs in your browser using JavaScript. Your sample text never leaves your device. No logging, no tracking, no server-side processing.
Is Colemak really faster than QWERTY?
For most English typists, Colemak achieves higher home row usage and lower same-finger bigrams than QWERTY. However, speed is determined more by practice hours than layout. Switching layouts typically causes a 3–6 month speed regression before you regain and then exceed your QWERTY speed.
What is a same-finger bigram (SFB)?
A same-finger bigram occurs when two consecutive characters are typed with the same finger. For example, typing 'ed' in QWERTY requires the middle finger to move from E to D. High SFB rates slow you down and increase repetitive strain. Dvorak and Colemak are specifically designed to minimize same-finger bigrams.
What is hand alternation in keyboard analysis?
Hand alternation measures how often consecutive keystrokes switch between the left and right hand. High alternation (like Dvorak) can feel rhythmic and comfortable. Lower alternation with more rolls (like Colemak) can feel fast for common English words. Both approaches have proponents.
What does home row usage percentage mean?
Home row usage is the percentage of keystrokes that land on the middle row (ASDF JKL; in QWERTY). High home row usage means less finger movement. Dvorak achieves around 70% home row usage for English text. QWERTY achieves around 32%. Colemak achieves around 74%.
What is the Colemak-DH variant?
Colemak-DH (also called Colemak Mod-DH) moves the D and H keys from the center columns to more comfortable positions on the bottom row. This addresses a common criticism that the inner index finger column of standard Colemak is awkward on row-staggered keyboards. Colemak-DH is increasingly popular for ergonomic keyboards.
Should I switch from QWERTY to a different layout?
Switching layouts is a significant time investment — expect 50–100 hours of practice before reaching your previous QWERTY speed. The payoff is reduced hand strain and, for many people, higher eventual speed. If you type for many hours daily or experience wrist/finger strain, learning an optimized layout may be worthwhile.
