If you want to ship oversized goods safely, in compliance with regulations and with reliable transit times, you need precise data on dimensions and weight limits - and a basic understanding of the relevant standards. In this guide to flatrack dimensions for 2025, you will find all the important dimensions, typical payloads, practical rules for weight distribution and a checklist for project planning.<\/h3>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What is a flat rack - and what is it suitable for?<\/h2>\n\n\n\n<p>A flat-rack container is a platform container without side walls and without a roof, usually with fixed or hinged end walls. This makes it possible to load extra-wide, extra-high or particularly heavy goods that do not fit into a standard box container (dry van). Typical applications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Construction machinery, agricultural machinery, industrial equipment<\/li>\n\n\n\n<li>Vehicles\/tractor units without trailers, boats\/yachts, tanks<\/li>\n\n\n\n<li>Modular components, steel girders, transformers<\/li>\n<\/ul>\n\n\n\n<p><strong>Advantages:<\/strong> Maximum width\/height clearance, precise load securing, crane or side loading possible.<br><strong>Attention:<\/strong> Exposed cargo (weather, swell), detailed securing and stowage plan required, possible out-of-gauge (OOG) surcharges.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Standards, ratings &amp; legal matters: What the numbers mean<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>ISO 668:2020<\/strong> specifies the external dimensions, tolerances and ratings (max. gross mass, \"R\") of ISO containers. Series 1 containers have a standardised width of 2,438 mm; standard lengths are 20 ft (6,058 mm) and 40 ft (12,192 mm). The ISO rating is generally specified up to 36,000 kg - higher values are permissible, provided the container is tested and labelled accordingly.<\/li>\n\n\n\n<li><strong>CSC badge (Container Safety Convention):<\/strong> All equipment used in international transport must carry a valid CSC safety plate. Among other things, you will find the permitted gross weight, test data and inspection notes on it.<\/li>\n\n\n\n<li><strong>Handling &amp; securing:<\/strong> Methods for handling, lifting and securing include ISO 3874 (Instructions for safe handling).<\/li>\n<\/ul>\n\n\n\n<p><strong>Important:<\/strong> The permissible gross weight (MGW\/rating) is not equal to the possible payload - tare (empty weight) and securing material are deducted. In addition, concentrated loads and stacking\/point load limits can significantly reduce the effective value. Shipping company specifications have priority.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Standard flatrack dimensions 2025: 20\u2032 &amp; 40\u2032 at a glance<\/h2>\n\n\n\n<p>The following typical dimensions are taken from current shipping company specifications (example: Hapag-Lloyd). Deviations are possible depending on the manufacturer\/series - always check the equipment specification of the line used.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Table 1: Typical flat rack dimensions &amp; weights (2025)<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameters<\/th><th>20\u2032 Flat rack (typical)<\/th><th>40\u2032 Flat rack (typical)<\/th><th>Source<\/th><\/tr><\/thead><tbody><tr><td>Internal length (between end walls)<\/td><td>approx. 5.64 m<\/td><td>approx. 11.65 m<\/td><td>Hapag-Lloyd 20\u2032 FR, Hapag-Lloyd 40\u2032 FR\/Platform<\/td><\/tr><tr><td>Width at floor\/deck<\/td><td>2,44 m<\/td><td>2,35 m<\/td><td>see above.<\/td><\/tr><tr><td>Width (narrowest point, between corner posts)<\/td><td>approx. 2.19-2.21 m<\/td><td>approx. 2.24-2.25 m<\/td><td>see above.<\/td><\/tr><tr><td>Usable height under front frame<\/td><td>approx. 2.23 m<\/td><td>approx. 2.26 m<\/td><td>see above.<\/td><\/tr><tr><td>Floor height (frame height)<\/td><td>~0,37 m<\/td><td>~0,65 m<\/td><td>see above.<\/td><\/tr><tr><td>Max.

The internal dimensions vary depending on the design and are not documented in ISO 668, but in the manufacturer\/reeder data sheets (see ISO note on internal dimensions).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Read weight limits correctly: Payload, point load &amp; distribution<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1) Gross vs. payload<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rating (R\/MGW):<\/strong> Maximum permissible gross mass (container + load + securing + accessories)<\/li>\n\n\n\n<li><strong>Tare:<\/strong> Unladen weight of the flat rack<\/li>\n\n\n\n<li><strong>Payload (payload):<\/strong> MGW - Tare - Securing material<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2) Uniform vs. concentrated<\/h3>\n\n\n\n<p>The permissible surface load is higher than point concentrate loads (e.g. under crawler tracks, machine feet). Use distributors (hardwood\/sleepers, steel plates) to transfer forces to the longitudinal and transverse beams.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3) Centre of gravity (COG) &amp; longitudinal distribution<\/h3>\n\n\n\n<p>Shipping companies often require the centre of gravity (x\/y\/z) to be specified. Position heavy components in the centre\/longitudinally above load-bearing cross beams; avoid overloading end frames or overhanging loads without support.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4) Lashing points &amp; friction<\/h3>\n\n\n\n<p>Flat racks offer lashing points with defined LC values. Calculate the required number of lashing devices (tie-down\/direct lashing) based on sea\/handling acceleration factors. Shipping company specifications (e.g. minimum number, angle, pre-tensioning force) are binding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5) Law &amp; documentation<\/h3>\n\n\n\n<p>The CSC sticker must be valid; securing\/handling must follow ISO 3874 principles, among others. Also check local road\/bridge limits for pre-\/post-carriage.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Width, height, length: What is \"OOG\" - and what is really possible?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Width:<\/strong> Over 2.44 m (deck width) to often &gt;3.5 m possible, depending on terminal, ship type and stowage space.<\/li>\n\n\n\n<li><strong>Height:<\/strong> Load may protrude beyond the front frame; pay attention to underlying deck structures, grab clearance and caster restrictions.<\/li>\n\n\n\n<li><strong>Length:<\/strong> Protrusions at the front\/rear are permissible, but must be carefully supported and secured.<\/li>\n\n\n\n<li><strong>Practice:<\/strong> Each OOG consignment is individualised - specify dimensions to the millimetre, send drawings\/photos, coordinate with the shipping company for approval.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Checklist: How to plan your flat rack shipment<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Measurement data &amp; documents<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Exact L \u00d7 W \u00d7 H (cm), gross weight, COG (sketch with reference to flat rack zero point)<\/li>\n\n\n\n<li>Photos\/drawings, loading points, lifting eyes, authorised lifting gear<\/li>\n\n\n\n<li>Requirements for weather\/transport protection (foil, bonnet, wood panelling)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Security &amp; stowage plan<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lashing concept (tie-down\/direct lashing, number\/BGW\/LC of belts\/chains, angle)<\/li>\n\n\n\n<li>Wooden supports\/support plates, anti-slip mats, edge protection<\/li>\n\n\n\n<li>Crane\/forklift planning, lifting gear, hook\/shackle sizes<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Operational approvals<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Confirm shipping company equipment (20\u2032\/40\u2032, fixed or folding bulkheads)<\/li>\n\n\n\n<li>Obtain OOG approval incl. stowage position (below\/on deck)<\/li>\n\n\n\n<li>Report VGM, check terminal cut-off<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Transit &amp; Routing<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compare departures\/arrivals: Timetables in real time<\/li>\n\n\n\n<li>Pre-carriage\/post-carriage checks (routes, bridge heights, authorisations)<\/li>\n<\/ul>\n\n\n\n<p><strong>Cost information:<\/strong> Specific prices depend on dimensions, weight, relation, season and OOG surcharges.

Our guide will help you weigh up the options: Flat rack vs. container: When is which worthwhile?<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ: Flat rack dimensions &amp; weights 2025<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What are the dimensions of a 20\u2032 flat rack?<\/h3>\n\n\n\n<p>Typical inside length approx. 5.64 m; width on deck 2.44 m; narrowest inside width between posts approx. 2.19-2.21 m; usable height under the front frame approx. 2.23 m. The exact values vary depending on the equipment; the data sheet of the shipping company (e.g. Hapag-Lloyd) is decisive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the dimensions of a 40\u2032 flat rack?<\/h3>\n\n\n\n<p>Inside length approx. 11.65 m; width on deck ~2.35 m; inside between posts ~2.24-2.25 m; usable height ~2.26 m (depending on line).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the weight limits?<\/h3>\n\n\n\n<p>ISO 668 specifies 36,000 kg as the standard rating; many flat racks are rated higher (e.g. 20\u2032 to 45,000 kg, 40\u2032 to 55,000 kg) if tested\/marked. The CSC plate and the shipping company specification are decisive. Payload = MGW - tare - securing material.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How much excess (OOG) is permitted?<\/h3>\n\n\n\n<p>Excess width &gt;2.44 m, excess height over the front frame and excess length are possible, but are subject to approval and stowage position (often on-deck) and incur surcharges.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need a crane?<\/h3>\n\n\n\n<p>Yes for most flat rack loads (crane\/reach stacker). Loading from the side is possible; plan lifting gear, lifting points and sufficient handling time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What information does the shipping company require?<\/h3>\n\n\n\n<p>Exact flatrack dimensions (L \u00d7 W \u00d7 H), gross weight, COG (with sketch), photos, lashing plan, desired equipment (20\u2032\/40\u2032, fixed\/folding end walls) and desired departure window (check timetables).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Where can I find official measurement bases?<\/h3>\n\n\n\n<p>The basic dimensions and ratings are described in ISO 668; detailed dimensions (internal dimensions, LC values etc.) can be found in the data sheet of the shipping company or the container manufacturer (e.g. Hapag-Lloyd specifications).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Flat racks are the logistical solution when width, height or weight go beyond the scope of standard containers. If you record dimensions to the millimetre, interpret weight limits correctly and plan load securing professionally, you reduce risks, costs and delays - especially for OOG shipments. Check departure options via the timetables and compare methods with <em>Flat rack vs. container: when is one worthwhile over the other?<\/em>.
