Why consulting slides formatting takes hours for consultants on Mac, and how to fix it

A consulting deck rarely starts from a blank file. You copy last month's deck, paste in new charts and pull slides from older projects. Each slide brings its own fonts, colors and spacing. Then someone has to pull all of it back into line with the brand guide. That pull back is where the hours go.

Where the hours actually go

Most people guess the time goes into writing. In practice, a lot of it goes into the fixing pass. You nudge a title a little to the left, match a gray that is almost right and reset a bullet indent someone set by hand. Each fix is small. Together they fill an afternoon.

• Re-typing brand colors because the exact values were never saved in the file
• Matching fonts on slides pasted in from an older template
• Moving logos and footers that drifted off their usual spot
• Fixing bullet indents and spacing one paragraph at a time
• Rebuilding charts so the palette matches the brand guide
• Checking the whole deck again after a reviewer changes one slide

What the hours cost in money

Start with the one figure that touches formatting time. It comes from a vendor blog, Imagine Layout, which cites a GfK survey for Made in Office. The blog says employees spend about 20 hours a month in PowerPoint, and roughly 8 of those on formatting. It does not link the original survey or give its year. Treat it as a rough signal, not a measured fact about consultants.

If you want a money number, you need a rate. The U.S. Bureau of Labor Statistics lists a median of $48.97 an hour for management analysts in its May 2025 data. Consultants may earn more or less, so swap in your own rate. Analyst pay is a proxy, not a consultant benchmark.

Multiply that by every person on the team, and the number grows quickly. Use it as a planning figure, not a payroll figure. Then test it. Track your own formatting time for a few weeks and compare the result with the table.

What the research says about slide design

The best study on this topic dates from 2013. Garner and Alley gave 110 engineering students slides built in one of two ways. One used assertion-evidence design. The other used PowerPoint default design. The assertion-evidence group had better comprehension, fewer misconceptions, lower perceived cognitive load and better delayed recall.

Be careful with what this proves. The study compared two design styles. It did not test off-brand fonts or colors, and it did not measure time spent fixing slides. The abstract gives no effect sizes, so do not quote one. Use it to justify clean, consistent design, not to promise a specific result.

Run a brand audit before you touch a slide

A short audit shows whether the problem sits in one deck or in the master. Run it on a deck that is nearly final. Do not start on a blank slide. Write down what you find, because the list becomes your fix list.

1. Open the brand guide and copy the exact color values and font names into one note.
2. Go to Design > Variants > Colors and check whether your brand colors are already in the list.
3. Go to View > Slide Master and note which fonts the master uses for titles and body text.
4. Scroll the deck and tag every slide that breaks a rule. Use one tag per problem, such as font, color or position.
5. Count the tags by type. A pile of font tags points at the master. Scattered tags point at the slides.
6. Save the audit next to the deck, so reviewers check the same list.

Mistakes that make slide formatting worse

• Pasting slides from another client deck without checking the master first.
• Using free text boxes for titles when the layout already has placeholders.
• Changing the font on one slide only, then calling the deck done.
• Letting every reviewer edit the master at the same time, with no owner.
• Trusting an old template because it looks close enough at a glance.
• Skipping the final pass because the meeting is close.

How Microsoft's brand tools fit in

Microsoft offers two routes. Theme colors and theme fonts live inside the file, so they cost nothing extra. Brand Kit is a Microsoft 365 Copilot feature. A brand owner uploads a template. When strict brand adherence is On, Copilot uses only that template and its slide master layouts.

Brand Kit has limits. Microsoft says Copilot does not change font or placeholder sizes. It may add design elements to fit extra content. Only the Brand Kit owner or a brand manager can change its settings, and end users cannot override them. Templates must be made in PowerPoint for Windows or Mac, not the web.

Microsoft also advises varied sample slides and text placeholders, rather than text boxes. Without enough sample slides, Copilot falls back to the Slide Master, which may give less optimal results. The same advice helps when you work by hand.

Where Lazur fits in

Lazur does not fix your formatting. It points at controls on your screen, explains what they do and guides you one click at a time. It also dictates text and drafts notes. That helps when you learn Microsoft's menus or walk a colleague through a fix. Every change still comes from your hand.

Here is a typical session. Open the deck and hold ⌥ ⌘ to ask where Customize Colors sits. Lazur circles it. You make the click, then ask what the next setting does. Lazur answers out loud while you work. For the wider setup, see PowerPoint for consultants on Mac.

Client data and your firm's rules

Slides often hold client names, figures and draft strategy. Before you paste any of it into an AI tool, check your firm's rules on client data. If your firm limits AI tools for client work, do the fixes by hand. Theme colors, theme fonts and the master need no outside service.

Next steps for a repeatable deck

If rebuilding old decks keeps eating your time, read how to stop rebuilding past consulting work from scratch. If a deck has the wrong page shape, check how to change slide size in PowerPoint on Mac. Both steps help the master do its job.
