To make conference talk slides look professional, design them for the back row of the room: one idea per slide stated in a short headline, type large enough to read on a projector, two or three numbers instead of a table, full-bleed photos instead of clip art, high contrast between text and background, and one consistent style from the title slide to the last. Keep the detail in your speaker notes, not on the slide — the audience should read a slide in a few seconds and then listen to you.

One idea per slide, in a headline the back row can read
A conference slide competes with your voice for attention. Write each headline as the point itself, short enough to read at a glance — our redesign rules keep a slide's main headline to 6–12 words, 14 at most — and move everything you'll say anyway into the speaker notes. If a slide needs a paragraph to make sense, it is two slides.

Make the title slide set the tone
The title slide is on screen while people find their seats, so it is the most-seen slide of your talk. Give it one strong photo, a large title and a clear step-down to the subtitle and your name. In the example below the title stayed the same, but the wording was lightly edited: “and” became “&”, “global layout” became “global expansion”, “2026.3” became “March 2026”, and a “Strategy Briefing 2026” label and a footer line were added. That is the kind of change to approve or undo before you present.

After: a large title over a full-bleed photo, wording lightly edited - 03
Replace tables with two or three big numbers
Nobody in a hall can read a table. Decide which two or three figures support your point, set them large with a short label, and put the full data in the appendix or a link. If you must show a comparison, use one simple chart that makes one comparison, and say the conclusion in the headline.

High contrast, full-bleed photos, one style throughout
Projectors wash out light colors, so keep strong contrast between text and background. Use real, full-bleed photos rather than icons scattered on white, keep one font family and two or three sizes, and reserve one accent color for the most important element on each slide. If your audience is international, keep the wording simple — BetterPPT keeps your original language and doesn't translate, and bilingual slides stay bilingual.

Who BetterPPT is for — and who it isn't
BetterPPT is an AI design agent that redesigns PowerPoint decks you've already written — every slide individually — and returns an editable .pptx. It's for decks where a lot is riding on it — investor meetings, client pitches, board updates, promotion reviews and conference talks — when your talk is written and the slides just look plain. It isn't for a class assignment or a routine team update: free tools like PowerPoint Designer or Canva's free plan are enough for those. It's paid — $39 for up to 30 slides, with a $9.90 refundable deposit to preview up to six of your slides first — and it supports 7 languages.

Questions
How big should text be on conference slides?
Big enough for the back row on a projector — larger than you'd use for a deck people read on their own screens. A practical test: show the slide on your laptop, step back a few metres, and check you can still read every word. If it doesn't fit at that size, cut words or split the slide rather than shrinking the type.
How many slides do I need for a 20-minute conference talk?
There is no fixed rule — it depends on your pace and how visual the talk is. Many speakers aim for roughly one slide per minute, using more slides only when each is a single image or number. Check the organizer's format and time limit first.
Can an AI tool redesign my talk slides without changing my wording?
Yes, if you choose how much it may change. BetterPPT has three modes — keep every word, allow light editing, allow restructuring. In the title-slide example above, the wording was lightly edited (“global layout” became “global expansion”), so review every slide before you present.
What does BetterPPT cost, and what are its limits?
$39 for up to 30 slides and $59 for 31–50 slides, one-time with no subscription; a refundable $9.90 deposit lets you see up to six redesigned slides first. It costs more than subscription tools and has no in-browser editor — you edit the returned .pptx in PowerPoint. It accepts .pptx files up to 50 slides and 50 MB.
Bottom line
Go through your talk once with only the headlines on screen: if they carry the argument, the design job is the rest. BetterPPT redesigns every slide individually and returns an editable .pptx — you decide how much of your wording may change, and a refundable $9.90 deposit shows you up to six of your own slides first.
