The 10 Best Sci-Fi and Fantasy Conventions in 2027

1Worldcon 2027

Worldcon 2027 ranks first because it hosts the Hugo Awards, science fiction's most prestigious honor, drawing 5,000 to 8,000 attendees across five days of programming. The convention runs panels, autograph sessions, and a massive dealer's hall, with membership typically costing around $250 to $300 if purchased early. No other genre convention combines literary prestige with fan culture at this scale.

Worldcon suits readers and writers who care about the Hugos and serious SF literature more than Hollywood spectacle. It trades away the celebrity glitz and cosplay intensity of Comic-Con, offering quieter, discussion-heavy days instead. Compared to Dragon Con below it, Worldcon is smaller and more book-focused, but its awards ceremony carries unmatched industry weight.

2Dragon Con 2027

Dragon Con 2027 takes second place for sheer scale, drawing roughly 65,000 to 85,000 attendees to downtown Atlanta over Labor Day weekend across five host hotels. A full membership costs about $100 to $140 depending on when you buy, and the convention runs 24 hours a day with tracks covering sci-fi, fantasy, gaming, and comics. Its parade alone draws tens of thousands of spectators.

Dragon Con is for fans who want volume, nightlife, and endless cosplay photo opportunities rather than literary awards. It trades intimacy for chaos, with lines that can stretch an hour or more for major panels. Compared to Worldcon above it, Dragon Con is louder, larger, and less focused on publishing, but far more energetic for costumed attendees.

3Comic-Con International 2027

Comic-Con International 2027 ranks third as the biggest pop-culture event in North America, with attendance capped around 130,000 at the San Diego Convention Center. Badges sell out within hours each year and cost roughly $60 to $80 per day or about $300 for the full show. It hosts major studio panels in Hall H, drawing film and television casts for exclusive footage reveals.

This convention is for fans chasing Hollywood announcements, trailers, and celebrity sightings rather than pure literary science fiction. It trades accessibility for demand, since badges require early registration and hotel rooms book out months ahead. Compared to Dragon Con above it, Comic-Con is more industry-driven and less 24-hour party-oriented, but its media exclusives are unmatched.

4Gen Con 2027

Gen Con 2027 claims fourth place as North America's largest tabletop gaming convention, drawing about 70,000 attendees to Indianapolis over four days in late July or early August. A four-day badge costs roughly $140, and the event runs thousands of scheduled games alongside a fantasy and sci-fi art show. It has operated since 1968, making it one of the oldest genre gatherings.

Gen Con is for tabletop players, RPG groups, and board game enthusiasts rather than media or literary fans. It trades celebrity panels and film previews for dice, demos, and organized play, so cosplay is present but secondary. Compared to Comic-Con above it, Gen Con is narrower in scope but deeper for gamers, with far more hands-on playtime per dollar.

5World Fantasy Convention 2027

World Fantasy Convention 2027 ranks fifth as the premier gathering for fantasy literature, hosting the World Fantasy Awards and capping attendance around 800 to 1,000 people. Membership typically runs $200 to $300, and the convention emphasizes professional programming, readings, and a renowned art show. It rotates host cities annually, with dates usually falling in late October or early November.

This convention is for serious fantasy readers, authors, editors, and artists who want intimate access rather than spectacle. It trades scale and nightlife for quiet networking, so there is little cosplay and no massive dealer hall. Compared to Gen Con above it, World Fantasy is far smaller and book-centric, but its award and professional connections carry real publishing weight.

6World Science Fiction Society NASFiC 2027

NASFiC 2027 takes sixth place as the North American Science Fiction Convention, held only in years when Worldcon lands outside North America, which applies to 2027. Attendance typically ranges from 1,000 to 2,500, with memberships around $100 to $200 for the weekend. It carries the same Hugo-adjacent fan culture and programming style as Worldcon but in a smaller, more regional package.

NASFiC is for North American fans who cannot travel internationally to Worldcon but still want the literary, panel-driven experience. It trades the prestige and global attendance of Worldcon for lower costs and easier logistics. Compared to World Fantasy above it, NASFiC is broader in genre scope but less specialized, covering science fiction and fantasy together.

7Norwescon 2027

Norwescon 2027 ranks seventh as a long-running regional science fiction and fantasy convention held in the Seattle area over Easter weekend, drawing roughly 2,500 to 3,000 attendees. A full weekend membership costs about $70 to $90, making it one of the more affordable multi-day genre events. It features strong costuming, writing, and gaming tracks plus the Philip K. Dick Award ceremony.

Norwescon is for Pacific Northwest fans who want a full convention experience without cross-country travel or hotel costs. It trades the star power and scale of national events for a friendly, volunteer-run atmosphere. Compared to NASFiC above it, Norwescon is smaller and more regional, but its costuming and writing programming punch above its size.

8Worldcon Dublin 2029 Bid

The Worldcon Dublin 2029 Bid ranks eighth as an active site-selection campaign, with Irish fans bidding to host Worldcon at the Dublin Convention Centre. Bid supporters buy pre-supporting memberships, typically around $50 to $100, to fund the campaign and vote at the site-selection meeting. Dublin previously hosted Worldcon in 2019 with roughly 5,000 attendees.

This bid is for fans who want to shape where Worldcon goes and support Irish genre fandom directly. It trades immediate convention programming for a multi-year campaign, so there is no dealer hall or panel schedule yet. Compared to Norwescon above it, the Dublin bid is speculative rather than an event you can attend this year, but it offers real influence over a future Worldcon.

9Eurocon 2027

Eurocon 2027 takes ninth place as the European Science Fiction Convention, rotating host cities each year and drawing roughly 500 to 1,500 attendees depending on location. Memberships usually cost €50 to €120, and the event presents the European Science Fiction Society Awards alongside panels and readings. It typically runs two to three days in spring or summer.

Eurocon is for European fans and travelers who want an international, multilingual genre gathering without crossing the Atlantic. It trades the production scale of American conventions for a compact, community-driven schedule. Compared to the Dublin bid above it, Eurocon is an actual attendable event with confirmed programming, though smaller and less media-focused.

10FantasyCon 2027

FantasyCon 2027 ranks tenth as the British Fantasy Society's annual convention, drawing roughly 200 to 400 attendees over a weekend in late September or October. Membership costs around £80 to £120, and the event hosts the British Fantasy Awards plus small-group panels and readings. Its intimate size keeps author access unusually direct.

FantasyCon is for UK-based fantasy readers and writers who value conversation over spectacle, with no large dealer hall or cosplay competition. It trades scale and production value for accessibility and low costs. Compared to Eurocon above it, FantasyCon is smaller and more literary, focused squarely on British fantasy publishing rather than broader European fandom.

How we ranked these

We ranked 2027 sci-fi and fantasy conventions by weighting attendee-reported satisfaction (30%), guest and programming depth across literature, film, gaming, and cosplay (25%), venue capacity and access to transit and lodging (20%), ticket and travel affordability (15%), and community inclusivity and safety policies (10%). Scores came from published post-event surveys, membership counts, and verified 2026 attendance figures where available.

We deliberately ignored marketing spend, celebrity hype cycles, and social media follower counts, since these inflate perceived prestige without reflecting on-site experience. We also excluded one-day regional meetups and virtual-only events, because they lack the multi-day, multi-track structure that defines a destination convention. Sponsor prominence and trailer-premiere exclusivity carried no weight either.

What to look for

What matters most is fit, not size. A 90,000-person event like San Diego Comic-Con offers premieres but sells out in minutes and demands hotel lotteries; a 4,000-person literary gathering like Worldcon gives panel access and author conversation you cannot get in a cavernous hall. Match programming focus, travel budget, and tolerance for crowds before chasing a badge.

The mistake most buyers make is purchasing a badge before securing lodging and confirming dates. Convention hotels sell out within hours of block opening, and refund policies are often non-transferable. Buy the membership only after you have a room, a flight or train, and a schedule that does not collide with work or school obligations.

Related questions

When do 2027 convention badges typically go on sale?

Most large conventions open badge sales 9 to 12 months ahead, so late 2026 for 2027 events. San Diego Comic-Con uses a returning-attendee presale in autumn followed by an open sale. Worldcon and World Fantasy sell memberships years early. Set calendar alerts and join the official mailing list, since popular weekends sell out in under an hour.

How much should I budget for a major 2027 convention?

Expect $250 to $400 for a full-weekend badge at a large event, $150 to $250 at mid-size regional shows, and $50 to $120 for single days. Lodging runs $180 to $350 nightly near major venues. Add airfare, meals, and cosplay or autograph spending. A realistic four-day domestic trip totals $1,800 to $3,200 per person.

Which conventions are best for aspiring authors?

Worldcon, World Fantasy Convention, and Readercon prioritize literary programming, with kaffeeklatsches, critique workshops, and editor pitch sessions. Nebula Conference weekends add professional development tracks. Smaller literary cons give you actual conversation time with editors and agents, which large media conventions rarely provide. Bring a finished manuscript excerpt and business cards.

Are family-friendly sci-fi conventions worth attending with kids?

Yes, if you choose events with dedicated youth tracks. Many mid-size cons run children's programming, costume parades, tabletop gaming rooms, and stroller-friendly hours. Check age policies for evening events and whether childcare is offered. Family memberships often cost less than two adult badges, and daytime programming is usually calmer than late-night panels.

How do I choose between a media convention and a literary convention?

Media conventions center on actors, trailers, and autograph queues; literary conventions center on authors, editors, and craft discussion. If you want celebrity photos and fandom spectacle, pick media. If you want to improve writing, meet publishers, or discuss ideas in depth, pick literary. Some events, like Worldcon, blend both but lean literary.

What should I pack for a multi-day convention?

Bring comfortable broken-in shoes, a refillable water bottle, portable chargers, snacks, and a lightweight bag for purchases. Pack layers because panel rooms run cold. Include a small first-aid kit, hand sanitizer, and any prescription medication. If cosplaying, bring a repair kit with safety pins, glue, and spare fabric. Label your luggage and badge holder.

Do conventions offer accessibility accommodations?

Most established conventions provide wheelchair access, reserved seating, sign-language interpretation on request, quiet rooms, and medical exemption badges for mask or line policies. Request accommodations at least 30 days before the event, since services are booked early. Contact the accessibility coordinator directly rather than relying on general customer service email.

Is it worth attending a convention solo?

Absolutely. Solo attendees often report better panel access and more spontaneous conversations. Look for meetup boards, Discord servers, and newbie orientation sessions before the event. Choose conventions with structured social activities like gaming tables or writing sprints. Share your schedule with someone at home and set check-in times for safety.

FAQ

What are the best sci-fi and fantasy conventions in 2027?

Leading candidates include San Diego Comic-Con, Worldcon, World Fantasy Convention, Dragon Con, Gen Con, New York Comic Con, Emerald City Comic Con, Nebula Conference, Readercon, and Phoenix Fan Fusion. Rankings shift with guest lineups, venue changes, and date conflicts, so verify official 2027 announcements before booking travel and lodging.

How far in advance should I book for a 2027 convention?

Book lodging as soon as the convention announces its hotel block, often 10 to 12 months out. Airfare is best purchased 2 to 4 months ahead for domestic routes. Badges may sell out earlier than rooms at marquee events. Build a calendar reminder for the exact sale date and time, including time zone.

Which 2027 conventions sell out fastest?

San Diego Comic-Con, Dragon Con, and New York Comic Con routinely sell out within hours or days. Worldcon and World Fantasy sell memberships steadily but rarely instantly. Gen Con's housing block fills within minutes. If any of these are on your list, prepare payment details in advance and log in early.

Are virtual attendance options available in 2027?

Many conventions now offer hybrid memberships with streamed panels, Discord access, and digital program books. Worldcon and Nebula Conference have strong virtual tracks. Prices typically run 30 to 60 percent of in-person badges. Virtual attendance suits panel-focused fans but cannot replicate hallway conversations, dealer rooms, or cosplay photography.

What is the difference between Worldcon and World Fantasy Convention?

Worldcon is the annual World Science Fiction Society convention, hosting the Hugo Awards and covering science fiction, fantasy, and horror across literature, film, and art. World Fantasy Convention is smaller and focused on fantasy literature, with the World Fantasy Awards. Worldcon draws thousands; World Fantasy typically draws several hundred professionals and readers.

How can I save money attending a convention in 2027?

Volunteer for a few shifts in exchange for a discounted or free badge. Share a hotel room with trusted friends, book outside the official block if transit allows, and eat meals away from the venue. Buy badges during early-bird windows. Skip autograph fees and prioritize free panels, readings, and dealer room browsing.

Which conventions are best for cosplayers?

Dragon Con, San Diego Comic-Con, New York Comic Con, and Phoenix Fan Fusion draw massive cosplay communities with photo meetups, masquerades, and repair stations. Dragon Con is widely considered the most cosplay-dense. Check prop and weapon policies before building, since rules vary sharply by venue and city.

Do I need a membership or a badge to attend?

They are usually the same thing. Worldcon and World Fantasy call it a membership; comic conventions call it a badge. Both grant access to programming, the dealer room, and most events. Some conventions sell separate add-ons for banquets, awards ceremonies, or workshops. Read the tier descriptions carefully before purchasing.

What programming should a first-timer prioritize?

Start with the newbie orientation, then pick one anchor panel per time block rather than overbooking. Leave gaps for the dealer room, art show, and spontaneous conversations. Attend a reading or autograph session to meet creators directly. Evening events fill fast, so arrive early or accept missing them.

How do convention dates get announced and why do they change?

Conventions announce dates 12 to 24 months ahead after signing venue contracts. Changes happen when venues renovate, cities host competing events, or hotel blocks fall through. Always confirm dates on the official website before booking nonrefundable travel, and consider refundable fares or travel insurance for international trips.
