How to Write Product Specifications Shoppers Trust

Shoppers leave when size or fit details are missing. Learn which specs to list, how to show product dimensions and when a comparison table helps.

Product specifications are measurable or verifiable facts about a product, such as a sofa’s assembled width, upholstery composition and packed dimensions. List the facts customers need to decide whether an item suits them, then show each value with its unit and variant.

A sofa can fit a living room yet fail to pass through the entrance. Your product page must distinguish the dimensions used for room planning from those used for delivery access.

Which Product Specifications to List by Category

Choose mandatory product specifications from the questions customers ask before buying, alongside any required product information. Start with recent emails, chat questions and returns reasons. A detail that changes whether someone can use the item belongs in the category’s required fields.

CategoryStarting spec setQuestion the details help answer
ApparelGarment measurements by size, fibre percentages, stretch, lining, care and fit descriptionWill this size and fabric suit me?
FurnitureAssembled and packed dimensions, weight, materials, seat measurements, load rating and assemblyWill it fit my room and delivery route?
ElectronicsModel number, dimensions, power input, connections, supported systems, capacity and included accessoriesWill it work with the equipment I already own?
BeautyIngredient list, net quantity, shade, application directions, storage and product warningsIs this the right product and format for my routine?

Use this sequence to turn those questions into a repeatable product-page format.

  1. Collect the supplier’s specification sheet, product label and instructions for the exact model or variant.
  2. Match each recurring customer question to a field. A doorway question needs packed dimensions and delivery configuration, not a bigger lifestyle image.
  3. Mark decision-changing fields as required for that category. Leave irrelevant fields out instead of copying the same checklist across every product.
  4. Fill the fields from the approved source and resolve conflicting figures before publishing.
  5. Read the page as a customer. Confirm you can answer the category’s buying questions without asking staff to look up missing data.

When a field is blank, request the missing figure from the supplier. Don’t convert a missing load rating into an estimate from a similar item.

How to Show Product Dimensions

Show product dimensions in metric units first, with the assembled item and each packed box listed separately. Name the axes beside the numbers, such as width × depth × height. Use the same axis order across the category.

For furniture, include seat height and seat depth where they affect comfort or use. List the product weight separately from shipping weight. For multiple cartons, give each carton’s dimensions and weight, plus what it contains.

Temple & Webster’s Montauk sofa page is a useful model for grouping specifications. It separates overall dimensions from seat dimensions and lists weight, upholstery composition and assembly requirements. Use those groupings as a model for your own table.

Add a dimension drawing and a photo beside a person or doorway for visual context. State any measurement tolerance supported by the supplier. A scale reference helps someone picture the item, but the written measurements decide the comparison.

This illustrative sofa table shows the distinction. The figures describe a fictional product.

SpecificationValue
Assembled width × depth × height210 × 90 × 82 cm
Packed width × depth × height214 × 94 × 70 cm, one carton
Product weight48 kg
Packed weight53 kg
LegsSupplied separately for assembly
Seat height44 cm

An illustrative customer question is, “Will this arrive in one box, and what are the box dimensions?” The table answers that question. It doesn’t prove the box will pass a particular doorway or turn through a narrow hallway. Customers also need to measure the clear opening and the full delivery route.

Fabric Guide and Materials Information

A fabric guide must give fibre content by percentage, fabric weight, stretch and a plain description of how the fabric feels. Specify whether stretch comes from the knit or weave, an elastic fibre or both. Describe the feel with words a customer can use, such as smooth, textured or brushed.

Copy material composition in the same order and percentages as the garment label. For an illustrative label reading “95% cotton, 5% elastane”, retain both fibres and those percentages online. Calling the same garment “pure cotton” changes the claim.

Give fabric weight in grams per square metre (g/m²) when the supplier provides it. Don’t invent a numerical weight from descriptions such as lightweight. Separate the outer fabric from lining or padding so customers know which component each composition describes.

Keep one shared fabric guide page and link each relevant product to it. The product page still needs its own composition and product-specific exceptions. Update the shared explanation once when terminology changes, then check that each linked product belongs to that fabric family.

For measurements that support clothing choices, connect the garment data to the advice described in the guide to fit finder tools.

Care Instructions Shoppers Ask About

Write care instructions as short actions customers can follow before and after purchase. A store’s shopping assistant needs the same product-specific care text when someone asks whether an item can be machine washed.

Covered clothing and textiles must meet the care labelling mandatory standard. The Consumer Goods (Care Labelling) Information Standard 2023 permits English instructions, the recognised international care symbols or both. Exemptions apply, including to second-hand goods and some accessories.

Publish the care label’s meaning in words on the product page, even when the physical label uses symbols. The online instructions must describe the same permitted treatment. A website saying tumble dry is safe conflicts with a label that prohibits it.

The ACCC’s care symbol guide explains the five families.

Symbol familyMeaning to repeat in words
WashtubWashing method and maximum temperature. Bars specify a gentler process.
TriangleWhether bleaching is allowed and which type is permitted.
SquareDrying method. A circle inside concerns tumble drying.
IronIroning conditions. Dots identify the permitted temperature level.
CircleProfessional cleaning conditions. Letters identify the permitted process.

A crossed-out treatment symbol prohibits that treatment. Translate the full symbol combination into words. A square by itself is insufficient to decide whether tumble drying is allowed.

For an illustrative cotton T-shirt whose approved label supports these treatments, care instructions could read as follows.

  1. Machine wash at a maximum of 30°C with similar colours.
  2. Do not bleach.
  3. Line dry in the shade. Do not tumble dry.
  4. Iron at a maximum of 150°C.
  5. Do not dry clean.

Cotton garments can shrink, and heat can affect the finished garment. Publish any tested shrinkage allowance supplied for that item. Don’t promise zero shrinkage or apply this example to every cotton product. A print, lining or finish can require different treatment.

Compatibility Charts for Parts and Accessories

Build a compatibility chart around the exact models, sizes or systems each accessory fits. Include the identifier customers can find on their existing product. A brand name alone is too broad when models use different connectors.

This fictional filter example shows how to distinguish fit from a similar-looking product.

AccessoryFitsRequired size or connectionExclusion
Filter AKettle K10 and K12Clip mount, 40 mm openingK10 Mini uses a different mount
Filter BKettle K20Twist mount, 45 mm openingDoesn’t fit K10 or K12
Filter CKettle K30Slide mount, 50 mm openingDoesn’t fit K20

Publish the chart as HTML text so search engines and AI assistants can read each row. Keep downloadable diagrams as supporting material. Where compatibility depends on a software version or adapter, place that condition in the row beside the supported model.

Installation Guides and Assembly Details

An installation guide must tell customers what they need before purchase, including tools, expected assembly time and whether licensed installation is required. State which fittings are included and which must be bought separately.

For a flat-pack cabinet, describe the number of people needed, the required tools and any wall-fixing requirement. For a product needing licensed electrical or plumbing work, state that requirement beside the installation information. Use the supplier’s stated assembly time with its assumptions about experience and preparation.

Link the full manual, but keep purchase-changing requirements on the product page. Customers must be able to find the clearance required for installation without downloading a long document.

Format Specs for People and Machines

Present specifications in a two-column table containing the field name and value, written as HTML text. Use consistent units within a category. An image of a table prevents customers from selecting the text and makes individual values harder for other systems to retrieve.

Keep those values in structured attributes as well as description copy. Store width as a number with a defined unit, then use that field to populate the visible table. Copying a width into several paragraphs creates several places to correct later.

The guide to product attributes explains the fields that hold these values. For search markup, use the guide to product schema to describe supported product facts. Markup must agree with the visible page and the selected variant.

If one variant has a different depth, show its value when that variant is selected. A shared parent description must not silently overwrite the variant’s specification.

Spec Sheets and Product Data Sheets

A spec sheet is a one-page summary of a product’s technical data. Provide a downloadable spec sheet for trade buyers or technical products when they need a document for quoting, procurement or an installation file. More detailed product data sheets can include performance tables and technical drawings.

Keep the figures that affect buying on the product page as text, including dimensions and compatibility. A PDF is useful to save or share, but it must not be the only place customers can find them.

Use this product spec sheet template. These headings identify the information to complete for each item.

  • Product name, model and variant
  • Dimensions and weight
  • Materials or composition
  • Technical performance and ratings
  • Compatibility and operating requirements
  • Installation and included parts
  • Care, warnings and limits
  • Document version and supplier contact

Here is a short illustrative spec sheet for a fictional freestanding side table.

HeadingExample entry

Generate the document from the same approved fields as the page. When a rating changes, update the download alongside the HTML text and remove the obsolete download from the active product page.

When a Product Comparison Table Helps

Compare three to five similar products when customers need to weigh differences within the same category. A sofa comparison is useful when the models differ in size, seating position or fabric care. A mixed table of sofas and dining chairs answers a different question.

Use one column per product and the same rows for every item. Include the current selling price with its tax basis, assembled dimensions, weight, material and the category’s deciding measurements. Add care, compatibility or installation requirements where they change the choice.

For sofas, seat height and seat depth help customers compare use as well as room fit. For accessories, supported model numbers can be the deciding row. Show “not supplied” when a figure is missing instead of inferring it from another model.

Populate comparison rows from the product records. Update the table when a variant, specification or price changes. Remove discontinued products from an active buying comparison. Compare like-for-like ratings so a per-seat load limit isn’t presented as equivalent to a whole-sofa limit.

Keep Specs Accurate Under Australian Consumer Law

Incorrect specifications can create a misleading product claim under Australian Consumer Law. The ACCC’s guidance on false or misleading claims says businesses must give accurate information and substantiate advertised claims. That includes website descriptions and performance claims.

A product that differs substantially from its description can have a major problem under consumer guarantees. Customers can then choose a refund or replacement, as explained in the ACCC’s guidance on remedies. Other problems have different remedies, so every incorrect figure doesn’t automatically create the same refund right.

Require supplier sign-off for technical figures such as wattage and load ratings before publishing them. Keep the source document and exact model beside the internal product record. Specify whether a load rating is per seat, per shelf or for the whole product.

Before publishing your next sofa page, compare its dimensions against the supplier sheet and the packed product. Check that the visible table, variant attributes and download all agree. If a customer still needs to email about delivery access, add the missing carton or assembly detail before using that page as the category’s model.
