The tech pack must define the bag state, the start and end landmarks, the measurement path and the parts included in the result. Otherwise a buyer, sample room and inspector can measure the same bag correctly according to three different interpretations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Start by separating finished dimensions from pattern or cut-part dimensions. Then decide whether the bag is measured flat, naturally standing, supported or filled with a defined reference load. Add an annotated point-of-measure diagram and a written method for every dimension that affects capacity, fit, access or alignment. Tolerances come after the method is controlled.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 counter-hierarchy ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#A_number_by_itself_is_not_a_finished-bag_specification\" >A number by itself is not a finished-bag specification<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Separate_finished_dimensions_from_pattern_dimensions\" >Separate finished dimensions from pattern dimensions<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Define_the_measurement_state_before_defining_width_height_and_depth\" >Define the measurement state before defining width, height and depth<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Define_width_using_the_part_of_the_bag_that_matters\" >Define width using the part of the bag that matters<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Define_height_without_accidentally_including_trim\" >Define height without accidentally including trim<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Define_depth_according_to_the_construction\" >Define depth according to the construction<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Build_every_measurement_row_from_the_same_five_elements\" >Build every measurement row from the same five elements<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Set_tolerances_only_after_the_method_is_repeatable\" >Set tolerances only after the method is repeatable<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#What_buyers_should_send_to_the_factory\" >What buyers should send to the factory<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Release_the_measurement_method_with_the_product_revision\" >Release the measurement method with the product revision<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-11\" href=\"https:\/\/bagslebon.com\/ar\/how-to-define-finished-bag-dimensions-in-a-tech-pack\/#Next_action\" >التالي action<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_number_by_itself_is_not_a_finished-bag_specification\"><\/span>A number by itself is not a finished-bag specification<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cBag size: 40 \u00d7 30 \u00d7 12 cm\u201d appears clear, but it leaves important decisions open:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Is width measured across the top opening, the widest body point or the base panel?<\/li><li>Does height include the handle, zipper arch, binding or only the body?<\/li><li>Is depth the gusset panel width, the finished side-wall projection or the maximum filled depth?<\/li><li>Is the bag empty, flattened, standing naturally or filled?<\/li><li>Are curved edges followed with the tape, or projected between two landmarks?<\/li><li>Is the tape applied straight, under light contact or pulled until the panel is smooth?<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The factory needs the design intent behind the number. The inspector needs a repeatable procedure. The buyer needs to know which dimension protects product fit or customer use.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/bagslebon.com\/wp-content\/uploads\/2026\/08\/finished-bag-dimension-landmarks.png\" alt=\"Annotated finished bag dimension landmarks for width, height and depth\"\/><figcaption class=\"wp-element-caption\">Label the physical landmarks. \u201cWidth\u201d becomes controllable only when everyone measures between the same points on the same bag state.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Separate_finished_dimensions_from_pattern_dimensions\"><\/span>Separate finished dimensions from pattern dimensions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pattern pieces are production inputs. Finished dimensions are product outputs. They are related, but they are not interchangeable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A cut panel may include seam allowance, turn-of-cloth allowance, binding allowance or material that disappears into a seam. A finished gusset may not project to the full cut width because its edges curve, fold or roll into the adjoining panels. Padding and lining can also change the internal space without changing the nominal outside dimension.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For quotation and sample approval, identify finished dimensions as finished measurements. If pattern or cut dimensions are also required, place them on a separate construction or pattern page. Mixing both types in one measurement table invites the sample room to treat the wrong value as the approval target.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Define_the_measurement_state_before_defining_width_height_and_depth\"><\/span>Define the measurement state before defining width, height and depth<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Soft bags do not hold one geometry in every condition. An unstructured tote can spread wider and become shorter when flattened. A padded case may spring back when released. A duffel can lengthen or bulge when filled. A zipper opening may pull the top edge into a different curve when closed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use one stated condition for each point of measure:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Flat and relaxed:<\/strong> placed on a surface without stretching or compressing the panel.<\/li><li><strong>Naturally standing:<\/strong> allowed to take its own shape, without hidden supports.<\/li><li><strong>دعمed:<\/strong> held in a defined position so the same landmarks can be reached.<\/li><li><strong>Filled:<\/strong> loaded with a specified reference item, fixture or filling method.<\/li><li><strong>Closed or open:<\/strong> zipper, flap, buckle and compression features set as stated.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The correct state depends on the buyer problem. A device sleeve should be checked in the condition that represents device insertion and closure. Overall appearance may be reviewed naturally standing. A flat promotional tote may be most repeatable when relaxed on a table.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/bagslebon.com\/wp-content\/uploads\/2026\/08\/flat-vs-filled-bag-dimensions.png\" alt=\"Flat and filled bag dimensions compared\"\/><figcaption class=\"wp-element-caption\">Flat and filled measurements answer different questions. Do not use one state for development and another for inspection without recording the change.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Define_width_using_the_part_of_the_bag_that_matters\"><\/span>Define width using the part of the bag that matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The top, middle and bottom of a bag may have different widths. A tapered tote can have a wide opening and a narrow base. A barrel bag may be widest through its curved middle. A bag with side seams that roll toward the front can make \u201cseam to seam\u201d different from the apparent front width.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Choose a width definition that protects the intended function:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>opening width for access;<\/li><li>internal clear width for product fit;<\/li><li>body width at a named height for silhouette;<\/li><li>base width for standing footprint;<\/li><li>panel width between construction seams for pattern relationship.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Mark the measurement line on the drawing. If it is taken at a stated distance above the base or below the opening, include that locator dimension as well.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Define_height_without_accidentally_including_trim\"><\/span>Define height without accidentally including trim<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Common height disagreements come from the top construction. One person measures to the highest zipper curve, another to the body edge, and another to the top of the binding. Handles and shoulder straps should normally have their own measurements rather than being absorbed into overall body height.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">State the lower landmark too. The bottom may be a fold, a piping centerline, a base seam or the lowest natural point of a rounded panel. On a bag with feet or molded protection, decide whether those parts are included in overall external height.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When usable internal height matters, define it separately. Outside height does not automatically equal internal clear height after foam, seams, zipper tape and base structure are assembled.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Define_depth_according_to_the_construction\"><\/span>Define depth according to the construction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Depth is especially easy to misread because \u201cgusset width\u201d can describe a panel, a finished side wall or the maximum projection of a filled bag.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a rectangular case, the finished outside depth may be measured between the front and back faces at a named position. For a tote with a bottom gusset, the useful decision may be the opened base depth. For a soft duffel, maximum filled depth may matter more than the relaxed empty profile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not assume a nominal gusset panel width becomes the same finished external depth. Seam take-up, piping, padding, curved joins and the way the bag is filled all affect the result.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Build_every_measurement_row_from_the_same_five_elements\"><\/span>Build every measurement row from the same five elements<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A usable measurement row contains:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Point ID:<\/strong> a stable code that also appears on the drawing.<\/li><li><strong>Measurement name:<\/strong> a short description of the controlled feature.<\/li><li><strong>Method:<\/strong> landmarks, path, bag state and closure condition.<\/li><li><strong>Target:<\/strong> the intended finished result and unit.<\/li><li><strong>Acceptance rule:<\/strong> tolerance or another approved evaluation method.<\/li><\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/bagslebon.com\/wp-content\/uploads\/2026\/08\/finished-bag-measurement-row.png\" alt=\"Elements of a controlled finished bag measurement row\"\/><figcaption class=\"wp-element-caption\">The drawing locates the point; the table records the method, target and acceptance rule. Neither document should be expected to carry the entire instruction alone.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If one point requires a special fixture, reference load or photograph, identify that supporting record in the row. Avoid separate files named \u201clatest measurements\u201d that are not tied to the tech-pack revision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Set_tolerances_only_after_the_method_is_repeatable\"><\/span>Set tolerances only after the method is repeatable<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A tighter tolerance does not repair an ambiguous measurement. It can make the argument worse because method variation is then mistaken for production variation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First ask two people to measure the same sample using the proposed instruction. If their results differ because they chose different landmarks, bag states or tape paths, improve the method. Then classify the point by consequence:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>interface and fit dimensions;<\/li><li>functional dimensions such as opening or adjustment range;<\/li><li>relationship dimensions such as paired pocket alignment;<\/li><li>general silhouette or appearance dimensions.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The appropriate control depends on material behavior, construction and consequence. There is no responsible universal tolerance for every soft-bag dimension. The related guide on <a href=\"https:\/\/bagslebon.com\/how-to-set-dimensional-tolerances-for-soft-bags\/\">setting dimensional tolerances for soft bags<\/a> explains this decision in more detail.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_buyers_should_send_to_the_factory\"><\/span>What buyers should send to the factory<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before requesting a sample or revised quotation, send:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>the current tech-pack revision and product code;<\/li><li>annotated views showing every point ID;<\/li><li>a measurement table with targets, units and methods;<\/li><li>bag state and closure condition;<\/li><li>internal versus external dimension labels;<\/li><li>critical contents, device sizes or fit interfaces;<\/li><li>any fixture, reference load or support method;<\/li><li>unresolved points requiring the manufacturer\u2019s proposal;<\/li><li>approval status of the latest physical sample.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/bagslebon.com\/wp-content\/uploads\/2026\/08\/bag-dimension-definition-checklist.png\" alt=\"Finished bag dimension definition checklist\"\/><figcaption class=\"wp-element-caption\">A complete measurement definition prevents the buyer, sample room and inspector from using different rules.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Release_the_measurement_method_with_the_product_revision\"><\/span>Release the measurement method with the product revision<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Changing a landmark, bag state or measurement path is a specification change even when the target number stays the same.
