Type the image height as a negative number if the image is inverted.<\/li>\n<li>In distance mode, enter the <strong>Object distance (u)<\/strong> and the <strong>Image distance (v)<\/strong>. Keep \\(v\\) positive for a real image and negative for a virtual one. Optionally fill in the object height so the calculator also reports the image size.<\/li>\n<li>Read the <strong>Magnification Results<\/strong>: the signed magnification \\(m\\), its absolute value \\(|m|\\), the image size as a percentage of the object, and \u2014 when an object height is given \u2014 the image height in several units.<\/li>\n<\/ol>\n<h2>What Is Magnification?<\/h2>\n<p>Magnification tells you how much larger or smaller an image is compared with the object that produced it, and in which orientation it appears. The linear (transverse) magnification \\(m\\) is a ratio of heights, so it has no units: \\(m = 3\\) means the image is three times as tall as the object, and \\(m = 0.5\\) means it is half as tall.<\/p>\n<p>The sign carries the orientation. A negative \\(m\\) means the image is inverted (upside down); a positive \\(m\\) means it is upright. For a single thin lens or mirror this sign also tells you the nature of the image: an inverted image is real \u2014 it can be projected onto a screen \u2014 while an upright one is virtual and can only be seen by looking through the lens or into the mirror.<\/p>\n<p>The two equivalent forms of the formula come from geometry. Rays drawn from the top of the object through the optical centre of the lens (or reflecting off a mirror) create two similar triangles, so the height ratio equals the distance ratio: \\(h'\/h = -v\/u\\). The minus sign exists because a real image, which lies on the opposite side of a lens (or in front of a mirror), is inverted relative to the object.<\/p>\n<p>In practice, magnification matters everywhere optics appears: choosing the objective of a microscope or telescope, designing a projector, sizing a magnifying glass, or checking the image formed by a camera lens. Combined with the image distance, it also lets you predict the size of the image on a sensor or screen from the size of the object alone.<\/p>\n<h2>Interpreting the Result<\/h2>\n<table>\n<thead>\n<tr>\n<th>Magnification<\/th>\n<th>Image size<\/th>\n<th>Orientation<\/th>\n<th>Nature (single lens\/mirror)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>\\(|m| &lt; 1\\)<\/td>\n<td>Reduced (smaller than the object)<\/td>\n<td>Depends on sign<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<tr>\n<td>\\(|m| = 1\\)<\/td>\n<td>Same size as the object<\/td>\n<td>Depends on sign<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<tr>\n<td>\\(|m| &gt; 1\\)<\/td>\n<td>Enlarged (larger than the object)<\/td>\n<td>Depends on sign<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<tr>\n<td>\\(m &lt; 0\\)<\/td>\n<td>\u2014<\/td>\n<td>Inverted<\/td>\n<td>Real<\/td>\n<\/tr>\n<tr>\n<td>\\(m &gt; 0\\)<\/td>\n<td>\u2014<\/td>\n<td>Upright<\/td>\n<td>Virtual<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li>The formulas apply to a <strong>single thin lens or a spherical mirror<\/strong> under the paraxial (small-angle) approximation. Thick lenses, compound systems and wide-angle rays introduce aberrations the simple ratio cannot capture.<\/li>\n<li>This calculator uses the <strong>real-is-positive sign convention<\/strong>: real objects and real images get positive distances. Some textbooks use the Cartesian convention, where the formula reads \\(m = v\/u\\) instead of \\(m = -v\/u\\) \u2014 check which convention your course uses before comparing answers.<\/li>\n<li>In height mode, the real-versus-virtual nature of the image cannot be decided from the heights alone; the calculator states the usual rule (inverted \u2192 real, upright \u2192 virtual for a single element), but multi-lens systems can break it.<\/li>\n<li>The <strong>linear magnification<\/strong> computed here is different from the <em>angular<\/em> magnification quoted for microscopes and telescopes, which compares viewing angles rather than heights.<\/li>\n<li>Keep the units consistent: the calculator converts each input from its chosen unit, so mixed units (e.g. object in cm, image in inches) are handled correctly.<\/li>\n<\/ul>\n<p>For more physics tools, try our <a href=\"https:\/\/wpcalc.com\/en\/physics\/kinematic-equations-solver\/\">Kinematic Equations Solver<\/a> or the <a href=\"https:\/\/wpcalc.com\/en\/physics\/conservation-of-energy-calculator\/\">Conservation of Energy Calculator<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enter the object and image heights, or their distances from a lens or mirror, to get the linear magnification, the image size, and whether the image is upright or inverted.<\/p>\n","protected":false},"author":3168,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[62],"tags":[87],"class_list":["post-65890","post","type-post","status-publish","format-standard","hentry","category-physics","tag-waves-optics"],"acf":[],"_links":{"self":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65890","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/users\/3168"}],"replies":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/comments?post=65890"}],"version-history":[{"count":1,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65890\/revisions"}],"predecessor-version":[{"id":65910,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/65890\/revisions\/65910"}],"wp:attachment":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/media?parent=65890"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/categories?post=65890"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/tags?post=65890"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
