Line card: what it is, and how to make one for a product range or a distributor

A line card is a one-sheet summary of what a company makes or carries. A buyer keeps it by the phone, a rep leaves it behind after a visit, and a purchasing agent scans it to decide whether you are worth a call. It is the shortest document in the sales stack, and the one most often read by someone who has never heard of you, so it has to answer “what do you do?” in the first few seconds. This guide covers the two kinds of line card, what belongs on each side, and the details that separate a card a buyer keeps from one that goes in the bin.

Two documents share the name

A product line card is a manufacturer’s card: the product categories you make, each with a picture, a one-line description and the series that fall under it. It answers “what do you make?” with images rather than numbers, and it points the reader to the data sheets for the detail. A distributor line card answers a different question, “which manufacturers do you represent, and are you authorized?”, with a wall of manufacturer marks grouped by category, each carrying its authorization status. The two look nothing alike, and building one from the other’s template is the most common line-card mistake. A third one-sheet about the company rather than a product, the capability statement, is for government and prime-contractor buyers and is a different document again.

What belongs on a product line card

• A headline that names the field you work in, not the company: “Instruments and final control for the process loop”
• One picture per category (a representative product, not a collage) with the category name, a one-line scope and the series it covers
• Certification marks that apply across the range (CE, UL, ISO 9001), so a buyer can rule you in before reading further
• Overleaf: the industries you serve, how you work (specification help, stock, warranty), and full contact details
• A pointer to where the numbers are: the data sheets, the catalog or the selection guide

What belongs on a distributor line card

The wall of marks is the whole front. Group the manufacturers by what they make (flow, pressure and level; valves and actuation; electrical and enclosures; control and networking) so a buyer with a brand in mind finds it in the right neighborhood. Mark every line with its status, and print the key once: authorized (a formal distribution agreement), stocking (authorized and held in inventory) and referral (you quote and coordinate, the manufacturer ships direct). The distinction matters to the buyer because it decides warranty, lead time and who they call when something goes wrong.

The back carries what the wall cannot: a territory map showing where you stock and where you carry select lines only, a table of branches with counter hours and cut-off times, the services you add (sizing and selection, panel build, calibration, documentation), the ordering terms and your contact details. A reader who found their brand on the front turns the card over to find out how to buy it.

Sizing manufacturer marks

A logo wall is a wall of other companies’ artwork, and the marks arrive in every shape: wide lockups, tall marks, square monograms. Scaled to the same box, a wide wordmark reads as huge and a square badge as tiny. The rule that makes a wall look even is to give every mark the same ink area, not the same width: a wide mark gets a shorter box, an upright mark a narrower one. Then clamp the few that would otherwise spill outside their tile. DataSheets Pro’s logo grid measures each uploaded mark and applies that rule for you; the manual version is the same arithmetic in a layout tool, one mark at a time.

Keeping it to one sheet

A line card is two sides of one sheet, and everything about it follows from that constraint. Half-inch margins, a slim header, one heading per category, and no paragraph longer than three lines. If the wall runs past the front, the fix is fewer lines per category on the card and the full list in the catalog or the price list, not a second sheet. Readers scan rather than read, and a line card is built entirely for scanning.

Keeping it current

A line card goes stale in two ways: a line is added or dropped, or a status changes when an agreement is signed or lapses. Because the card is short, the temptation is to leave the old PDF up. Keep the card in a structured document you can regenerate, with the marks, statuses and territory as data rather than artwork pasted into a page, and reissue it with a date on the footer. A distributor line card with an effective date is one a buyer can trust; one without is one they double-check by phone.
