A 15 minute typing test is the endurance version. It shows how well you can type accurately for an extended time, similar to real work or study writing.
This duration reveals true consistency. It shows whether your speed stays steady, whether accuracy drops with fatigue, and whether your posture and technique hold up.
Stay relaxed, keep shoulders down, and use gentle key presses. If you feel tension, slow slightly for a few lines—steady typing beats short bursts in long tests.
Focus on correct words and clean spacing. In long tests, one repeated mistake pattern can lower accuracy quickly, so stay mindful of your common weak spots.
Use this test if you want a long benchmark, job practice, or serious endurance training. It is best done when you have time and can focus without interruptions.
