<p>In order to determine the height that the TV should be mounted, we first need to know the size of the TV, the viewing distance from the TV, the eye level height from the floor and the reclining sitting angle. Let me bring some easy to follow formulas and then I will explain them:</p>
<p><strong>Optimum Viewing Distance (OVD)</strong> is the distance from where you should be sitting, to the wall of where the TV will be mounted. You can find the VD if you know your <strong>TV Size (TVS)</strong> from the following formula:</p>
<p><strong>(1)Optimum Viewing Distance (OVD)=TVS*1.82</strong></p>
<p>For example if your TV size (TVS) is 55in then the Optimum Viewing Distance (OVD) should be 100 inches (55*1.82).</p>
<p>Before we can calculate the <strong><a title="Flat Screen TV Installation at the best Height" href="http://www.nextdaytechs.com/csubtype/Flat_Screen_TV_Installation.html">TV Installation Height </a> (TVIH)</strong> we need to measure your <strong>Eye Level Height (ELH)</strong> from the floor, while you a sitting down on your couch. Once you measure your <strong>ELH</strong> we can find the <strong>TVIH</strong> by the following formula:</p>
<p><strong>(2)TV Installation Height (TVIH)</strong> <strong>=ELH+(OVD*0.22)&#8211;To the Midpoint of the TV.<br />
</strong></p>
<p>For example when I sit on my couch my <strong>ELH</strong> from the floor is 39 inches and the O<strong>VD</strong> is 100 inches (see previous example) so my <strong>TVIH</strong> is 39+(100*0.22)=61 inches from the floor to the midpoint of the TV. So here is a table:</p>
<p>TV Size (in) Viewing Distance (in) TV Installation Height (in) at ELH=39in</p>
<p>32 58 (4.8ft) ELH+13 about 52 in</p>
<p>37 67 (5.6ft) ELH+15 about 54 in</p>
<p>42 76 (6.4ft) ELH+17 about 56 in</p>
<p>46 84 (7.0ft) ELH+18 about 57in</p>
<p>55 100 (8.3ft) ELH+22 about 61 in</p>
<p>65 118 (10.0ft) ELH+26 about 65 in</p>
<p>70 127 (10.6ft) ELH+28 about 67 in</p>
<p> ;</p>
<p>Formula 1 is based to about 30 degrees of viewing angle that are within the limits of the Society of Motion Picture and Television Engineers, THX and manufacturers’ recommendations for 16:9 HDTV’s.</p>
<p>Formula 2 is based on the average reclining angle of about 12.5 degrees from vertical ( sitting up straight) for casual sitting. Manufacturers range for casual sitting is 10-15 degrees.</p>
