It&rsquo;s a frustrating (and costly) surprise, and it usually comes down to one mix-up: inside vs. outside dimensions.<\/span><\/p>\n<p><span data-contrast=\"auto\">Every box has two sets of measurements. Inside dimensions tell you what fits. Outside dimensions tell you how much space the packed box takes up in transit and in storage. Mix them up and you could end up with a box that&rsquo;s too tight, or a shipping bill you didn&rsquo;t plan for.<\/span><\/p>\n<p><span data-contrast=\"auto\">In this Packlane guide, we outline the difference, explain when to use each, and walk you through how to measure a box accurately.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"TextRun SCXW115043108 BCX8\" lang=\"EN-US\"

This is why most packaging manufacturers, including Packlane, list inside dimensions for custom boxes.<\/span><\/p>\n<p><span data-contrast=\"none\">When choosing a box, don&rsquo;t measure the outside and assume your product will fit.&nbsp; The walls take up space, so the interior is always slightly smaller than the exterior.<\/span><\/p>\n<p><span data-contrast=\"none\">Always compare your product&rsquo;s dimensions to the inside Length x Width x Depth (L x W x D) to ensure there&rsquo;s enough room for the product and any protective materials you&rsquo;ll be using, such as bubble wrap, foam inserts, tissue paper, or dividers. Using inside dimensions helps reduce product movement during transit, minimizes the need for excess filler materials, and creates a cleaner, more professional unboxing experience.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"TextRun SCXW180254230 BCX8\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW180254230 BCX8\">What <\/span><span class=\"NormalTextRun SCXW180254230 BCX8\">a<\/span><span class=\"NormalTextRun SCXW180254230 BCX8\">re <\/span><span class=\"NormalTextRun ContextualSpellingAndGrammarErrorV2Themed SCXW180254230 BCX8\">o<\/span><span class=\"NormalTextRun ContextualSpellingAndGrammarErrorV2Themed SCXW180254230 BCX8\">utside<\/span> <span class=\"NormalTextRun SCXW180254230 BCX8\">b<\/span><span class=\"NormalTextRun SCXW180254230 BCX8\">ox <\/span><span class=\"NormalTextRun SCXW180254230 BCX8\">d<\/span><span class=\"NormalTextRun SCXW180254230 BCX8\">imensions?<\/span><\/span><\/h2>\n<p><span class=\"TextRun SCXW227829923 BCX8\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW227829923 BCX8\">Outside box dimensions measure the overall size of <\/span><span class=\"NormalTextRun SCXW227829923 BCX8\">a fully<\/span> <span class=\"NormalTextRun SCXW227829923 BCX8\">assembled box.<\/span><span class=\"NormalTextRun SCXW227829923 BCX8\"> These measurements <\/span><span class=\"NormalTextRun SCXW227829923 BCX8\">are taken from edge to edge and <\/span><span class=\"NormalTextRun SCXW227829923 BCX8\">include the thickness of the corrugated or paperboard material.<\/span><span class=\"NormalTextRun SCXW227829923 BCX8\"> Unlike inside dimensions, outside dimensions <\/span><span class=\"NormalTextRun SCXW227829923 BCX8\">aren&rsquo;t<\/span><span class=\"NormalTextRun SCXW227829923 BCX8\"> used to <\/span><span class=\"NormalTextRun SCXW227829923 BCX8\">determine<\/span><span class=\"NormalTextRun SCXW227829923 BCX8\"> whether a product fits.

Assemble the box fully first, then follow these steps:<\/span><\/p>\n<p><span data-contrast=\"none\">Step 1: Measure the length<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Identify the longest side of the box opening and measure from one inside wall to the other. Record it as length.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Step 2: Measure the width<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Measure the shorter side of the opening from one inside wall to the opposite side. Then, write it down as the width.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Step 3: Measure the depth<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">To get the depth, measure from the inside bottom of the box straight up to the top edge. This is sometimes referred to as the height, although most packaging manufacturers, including Packlane, use the term depth.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Step 4: Record measurements in the correct order<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Always list measurements as: Length x Width x Depth (L x W x D)<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">Using the correct order helps avoid confusion when ordering packaging or comparing box specifications.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<p><span data-contrast=\"none\">For a detailed walkthrough, read our <\/span><a href=\"http:\/\/packlane.com\/blog\/how-to-measure-box-dimensions-correctly\/\"><b><span data-contrast=\"none\">How to Measure Box Dimensions Correctly (Length x Width x Depth<\/span><\/b><\/a><span data-contrast=\"none\"> article.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"TextRun SCXW95872030 BCX8\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW95872030 BCX8\">Best practices for <\/span><span class=\"NormalTextRun SCXW95872030 BCX8\">accurate<\/span><span class=\"NormalTextRun SCXW95872030 BCX8\"> measurements<\/span><\/span><\/h2>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"&#61623;\" data-font=\"Symbol\" data-listid=\"1\" data-list-defn-props='{\"335552541\":1,\"335559685\":720,\"335559991\":360,\"469769226\":\"Symbol\",\"469769242\":[8226],\"469777803\":\"left\",\"469777804\":\"&#61623;\",\"469777815\":\"hybridMultilevel\"}' data-aria-posinset=\"1\" data-aria-level=\"1\"><span data-contrast=\"none\">Measure from the inside walls, not the outside edges.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"&#61623;\" data-font=\"Symbol\" data-listid=\"1\" data-list-defn-props='{\"335552541\":1,\"335559685\":720,\"335559991\":360,\"469769226\":\"Symbol\",\"469769242\":[8226],\"469777803\":\"left\",\"469777804\":\"&#61623;\",\"469777815\":\"hybridMultilevel\"}' data-aria-posinset=\"2\" data-aria-level=\"1\"><span data-contrast=\"none\">Use a rigid ruler or tape measure for accuracy.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"&#61623;\" data-font=\"Symbol\" data-listid=\"1\" data-list-defn-props='{\"335552541\":1,\"335559685\":720,\"335559991\":360,\"469769226\":\"Symbol\",\"469769242\":[8226],\"469777803\":\"left\",\"469777804\":\"&#61623;\",\"469777815\":\"hybridMultilevel\"}' data-aria-posinset=\"3\" data-aria-level=\"1\"><span data-contrast=\"none\">Measure products after they&rsquo;ve been wrapped if protective packaging will be used.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"&#61623;\" data-font=\"Symbol\" data-listid=\"1\" data-list-defn-props='{\"335552541\":1,\"335559685\":720,\"335559991\":360,\"469769226\":\"Symbol\",\"469769242\":[8226],\"469777803\":\"left\",\"469777804\":\"&#61623;\",\"469777815\":\"hybridMultilevel\"}' data-aria-posinset=\"4\" data-aria-level=\"1\"><span data-contrast=\"none\">Double-check measurements before placing custom packaging orders.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-setsize=\"-1\" data-leveltext=\"&#61623;\" data-font=\"Symbol\" data-listid=\"1\" data-list-defn-props='{\"335552541\":1,\"335559685\":720,\"335559991\":360,\"469769226\":\"Symbol\",\"469769242\":[8226],\"469777803\":\"left\",\"469777804\":\"&#61623;\",\"469777815\":\"hybridMultilevel\"}' data-aria-posinset=\"5\" data-aria-level=\"1\"><span data-contrast=\"none\">Allow for a little wiggle room.
