10 Common Typing Speed Mistakes Holding Back Your WPM

Typing is a physical motor skill, much like playing a musical instrument or swinging a tennis racket. In any physical skill, bad technique limits how far practice can take you. If a golfer has a fundamental flaw in their grip, swinging 1,000 times a day will not fix the issue—it will simply lock in bad muscle memory.

The same rule applies to keyboard practice. Many typists hit speed plateaus for months because they repeat bad habits without realizing it. In this guide, we break down the 10 most common typing speed mistakes, explain why they destroy your WPM, and provide actionable solutions.

Mistake 1: Glancing Down at the Keyboard

Even typists who claim to touch type often have a subtle habit of glancing down at their hands whenever they encounter a difficult word or symbol.

Why it hurts WPM: Every glance down interrupts screen focus. Your eyes take roughly 0.3 seconds to refocus on the desk and another 0.3 seconds to return to the monitor. Glancing down 10 times during a test wastes 6 full seconds of typing time.

The Fix: Feel for the raised ridges on F and J. If you make a mistake, force yourself to find the key blindly without looking down.

Mistake 2: Resting Wrists Heavy on the Desk

Resting the heels of your palms or wrists firmly on your desk or laptop surface while typing locks your hand motion.

Why it hurts WPM: When wrists are anchored to the desk, your fingers must stretch awkwardly to reach top and bottom row keys. This creates tendon strain and reduces finger reach by up to 40%.

The Fix: Float your wrists neutral and level with your keyboard, keeping hands slightly elevated like a piano player.

Mistake 3: Thumb Misuse & Index Finger Space Bar Striking

Some typists hit the Space Bar using an index finger instead of a thumb, or fail to use their dominant thumb consistently.

Why it hurts WPM: Using an index finger for the Space Bar pulls your hand out of Home Row position, forcing you to relocate F or J after every single word.

The Fix: Rest both thumbs lightly over the Space Bar. Use your dominant thumb to strike the space bar at the end of every word.

Mistake 4: Over-Reliance on Backspace & Panic Typing

Making a typo, panicking, and holding down Backspace to erase three whole words instead of carefully deleting the bad letter.

Why it hurts WPM: Indiscriminate backspacing destroys your Net WPM score. Read our detailed analysis on The Backspace Penalty and WPM Math.

The Fix: When you make a mistake, stop instantly. Press Backspace deliberately for each wrong letter, re-orient on Home Row, and continue cleanly.

Mistake 5: Neglecting Weak Pinky Keys (Q, Z, P)

Avoiding the use of pinky fingers and reaching across with ring or middle fingers to press P, Q, Z, or Shift.

Why it hurts WPM: Over-stretching middle fingers to cover pinky keys distorts your hand posture and causes frequent typos on common words containing P or Q.

The Fix: Dedicate 3 minutes of daily warm-up practice exclusively to pinky drills on Tyspingo (e.g. apa, aqa, aza, ;p;).

Mistake 6: Cadence Breaking (Bursting then Pausing)

Typing familiar words extremely fast, then completely stopping when hitting a complex word like thoroughly or accommodate.

Why it hurts WPM: Erratic bursts break mental flow and cause hand tension. Smooth, metronome-like typing produces higher average WPM than fast erratic bursts.

The Fix: Read our guide on Speed-First vs. Accuracy-First Training to learn rhythm cadence building.

Mistake 7: Practicing Only Simple & Familiar Texts

Repeatedly typing short, simple sentences or familiar paragraphs that contain only common 3-letter words.

Why it hurts WPM: It creates false confidence. When confronted with real-world emails, technical documents, or exams, your speed collapses.

The Fix: Use Tyspingo Custom Text Practice to paste work reports, college notes, or news articles into your daily drills.

Mistake 8: Skipping Punctuation & Number Row Drills

Ignoring numbers (1 2 3 4 5 6 7 8 9 0) and punctuation (? ! ; : " ' -) during daily practice.

Why it hurts WPM: In real life, text contains uppercase letters, quotes, commas, and numbers. If you stumble every time a number appears, your overall productivity plummets.

The Fix: Include number row and punctuation sentences in your weekly practice routine.

Mistake 9: Poor Ergonomic Chair & Monitor Alignment

Slouching, craning your neck forward, or typing on a keyboard positioned too high or too low relative to your elbows.

Why it hurts WPM: Physical discomfort causes shoulder tightness, finger stiffness, and fatigue within 10 minutes of typing.

The Fix: Adjust your chair so elbows rest at 90 degrees and the top of your monitor is aligned with your eye level.

Mistake 10: Marathon Fatigue Sessions vs Short Daily Drills

Practicing for 2 hours on Sunday afternoon, then doing zero practice for the rest of the week.

Why it hurts WPM: Motor memory requires frequent neurological reinforcement. Fatigue during long sessions locks in sloppy, tired mistakes.

The Fix: Practice for 15 to 20 minutes every single day following our 30-Day Typing Speed Improvement Plan.
