The typical human reaction time to a visual signal is around 200 to 300 milliseconds; most people average about 250 ms on tests like this.<\/p>\n<h2>How to take the reaction time test<\/h2>\n<ol>\n<li>Click the blue box. It turns red: wait, and don&#8217;t click yet.<\/li>\n<li>After a random delay of 1.5 to 4.5 seconds it turns green. Click (or tap, or press Space) as fast as you can.<\/li>\n<li>Your time appears in milliseconds. Clicking while red counts as too soon and is not recorded.<\/li>\n<li>Do five tries. Your average is more reliable than a single lucky click.<\/li>\n<\/ol>\n<h2>What is a good reaction time?<\/h2>\n<table class=\"qt-ref\">\n<thead>\n<tr>\n<th>Average<\/th>\n<th>Rating<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Under 180 ms<\/td>\n<td>Exceptional; often helped by anticipation<\/td>\n<\/tr>\n<tr>\n<td>180 to 230 ms<\/td>\n<td>Faster than average<\/td>\n<\/tr>\n<tr>\n<td>230 to 290 ms<\/td>\n<td>Average<\/td>\n<\/tr>\n<tr>\n<td>290 to 400 ms<\/td>\n<td>Slower than average<\/td>\n<\/tr>\n<tr>\n<td>Over 400 ms<\/td>\n<td>Slow, or distracted<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Your result also includes your device&#8217;s delay.

In sports and esports, a few milliseconds can decide who wins.

Compare results on the same device.<\/p>\n<h3>Can I improve my reaction time?<\/h3>\n<p>Good sleep, practice and focus help.
