Vetting a Cover Designer's Portfolio: Red Flags Before You Hire

Published July 6, 2026 — Design Guides

A beautiful portfolio tells you a designer can produce beautiful individual images. It tells you almost nothing about whether they'll deliver a print-ready file that meets your platform's spine spec, respond to revision requests within a reasonable timeframe, or hold to the price they initially quoted. Authors who've been burned by a bad hiring decision almost always describe a portfolio that looked fine going in — the problems showed up in the parts of the process a portfolio doesn't display.

Check Whether the Portfolio Shows Real, Published Books

Search for a handful of the titles shown in a designer's portfolio on Amazon or another retailer. A surprising number of low-cost marketplace designers display mockup covers for books that were never actually published, or that were self-commissioned practice pieces rather than paid client work. This isn't automatically disqualifying — everyone starts somewhere — but it changes what the portfolio is actually telling you. A portfolio full of real, findable, published books with visible sales rank or reviews demonstrates the designer has been through full production cycles with real clients and real platform requirements, which is a meaningfully different qualification than aesthetic skill alone.

While you're checking, look at whether the published books span more than one genre convincingly. A designer whose portfolio is all fantasy, all executed in a similar illustrated style, may be genuinely excellent at that specific niche but a poor fit if your book is contemporary romance or business nonfiction, where the visual conventions and reader expectations are entirely different — the genre distinctions covered in genre cover design conventions matter just as much when hiring as when designing yourself.

Ask About Revisions and File Delivery Before You Pay Anything

Get the number of included revision rounds, what happens if you need changes beyond that number, and exactly what file formats you'll receive at the end, in writing, before any money changes hands. A common and costly surprise: a designer delivers only a flattened JPEG or PNG suitable for an ebook thumbnail, with no editable source file and no print-ready wraparound version, leaving the author unable to make even minor future edits or produce a matching print cover without paying for an entirely new commission. This is a reasonable thing to specify clearly in your initial brief to a cover designer, and a designer's willingness to answer these questions clearly and in writing before taking a deposit is itself useful signal about how the rest of the working relationship will go.

Be specific about timeline expectations too. Vague answers like "usually a few weeks" from a designer who won't commit to an actual delivery date, especially for a paid rush order, are a common precursor to missed deadlines that can derail a planned launch date.

Watch for Stock-Heavy Portfolios Presented as Custom Illustration

Some lower-cost designers assemble covers entirely from licensed stock photography and stock illustration elements, which is a completely legitimate and often smart approach for a budget project, but becomes a problem if it's misrepresented as fully custom illustration at a price point that assumes original artwork. Ask directly whether a given portfolio piece used stock elements, and if so, whether the specific license covers your intended use and print run size — this connects directly to the licensing questions covered in stock photo license types, since the designer's license, not just yours, may govern what you're actually allowed to do with the final file.

Payment Structure and Recourse

Full payment upfront with no milestone structure is a common practice among reputable freelance designers, so it isn't automatically a red flag on its own — but it does mean you have less leverage if the work falls short. A 50 percent deposit with the balance due on delivery of an approved concept gives you more practical recourse than paying in full before seeing any draft, particularly with a designer you have no prior relationship with or verifiable review history for. The Federal Trade Commission publishes general guidance on vetting contractors and freelancers and recognizing common scam patterns in service-based hiring, which applies just as directly to hiring a cover designer as it does to any other contracted service: ftc.gov/business-guidance.

Reading Reviews and Testimonials Skeptically

Reviews posted directly on a designer's own website or marketplace profile are the easiest thing to curate selectively, so treat them as a starting point rather than a verdict. Where possible, look for mentions of the same designer in author forums, self-publishing Facebook groups, or writer community discussion threads where the conversation wasn't initiated or moderated by the designer themselves. A pattern of specific, detailed complaints about missed deadlines or unresponsive communication across multiple independent sources carries far more weight than the absence of negative reviews on a profile the designer controls.

It's also worth asking a prospective designer directly for one or two past clients you can contact, rather than relying only on testimonials they've chosen to publish. A designer confident in their track record will usually accommodate a reasonable request like this; reluctance to provide any verifiable reference at all, especially for a larger commission, is itself useful information before you commit a deposit.
