How to make Harvey balls in PowerPoint
Harvey balls in PowerPoint are built two ways without installing anything extra. The fastest is the native Pie shape, whose adjustment handle sets the fill angle in 25 percent steps. The second is typing a Unicode circle character directly into a text box. Both methods produce clean, on-brand icons in under a minute, with no add-in required.
What Harvey balls are and when to use them
A Harvey ball is a circle filled to a set percentage: empty, a quarter, half, three-quarters, or full. Analysts use a row of them to rate several options against the same criteria without writing out a score for every cell. A reader scans the fill level and reads the verdict in under a second.
They show up most often in capability assessments, vendor comparisons, and competitive landscapes, wherever a grid compares several items across several dimensions. A finance team might rate five software vendors against ten requirements. A strategy team might rate a company's readiness across six capability areas. In both cases, the Harvey ball carries the judgment, and the surrounding text explains it. For a full worked example of that kind of grid, see our guide to building a competitive landscape slide.
Method 1: build Harvey balls with PowerPoint's Pie shape
The Pie shape is the most flexible native method. It is a real vector shape, so it resizes cleanly, takes any fill color, and groups into a set you can copy down a whole column. Here is the four-step build.
Insert the shape. Go to Insert, Shapes, and choose Pie from the Basic Shapes group. Draw it while holding Shift so the width and height match exactly, giving you a true circle.
Set the fill angle. Drag the shape's small yellow adjustment handle around the circle's edge. A quarter turn fills 25 percent, a half turn fills 50 percent, and a full turn fills 100 percent.
Recolor to match your palette. Select the shape, open Shape Format, and set the fill to your accent color. Leave the outline a thin, neutral gray so every circle in the row reads as one consistent set.
Build the full set and lock it. Repeat for 0, 25, 50, 75, and 100 percent, align the five on one horizontal guide, then group them and save the group to your personal shape library.
The standard five-level Harvey ball scale: 0, 25, 50, 75, and 100 percent fill.
Method 2: insert Harvey balls as Unicode circle characters
If you just need a quick set of icons in a text box or a grid cell, skip the shape entirely. Five Unicode characters already draw the exact fill levels: ○ ◔ ◑ ◕ ●.
Open the Symbol dialog. Click Insert, then Symbol, and search the font Segoe UI Symbol for "circle." The four partial-fill glyphs sit next to the plain empty and full circles.
Copy the set once. Copy all five characters, ○ ◔ ◑ ◕ ●, into a spare text box. Typing them from the symbol map every time is slow, so keep this row as a master to copy from.
Paste into each cell. Paste the matching character into each rating cell, then increase the font size to roughly 20 to 24 points so the fill level reads clearly at a glance.
Color for emphasis only. Leave the fill in your default body text color. Reserve a second color for the one rating you specifically want a reader's eye to land on first.
Building a full Harvey ball comparison grid
A single Harvey ball rarely appears alone. Most decks use a full grid: criteria down the rows, options across the columns, one Harvey ball per cell. Three habits keep that grid readable.
Keep every circle the same size, since one that drifts larger or smaller looks unfinished and makes small differences hard to compare. Fill in one direction only, starting at 12 o'clock and moving clockwise, the convention most readers already recognize. Cap the scale at five levels. Empty, quarter, half, three-quarter, full is enough resolution for almost any rating, and a finer scale just forces the reader to squint at fill angles instead of scanning the pattern.
A generic three-by-three example. Swap in your own criteria and options; the fill pattern is what a reader actually scans.
Common Harvey ball mistakes to avoid
Most of these come down to consistency: one fill direction, one accent color, one scale, applied identically down every row and across every column. That consistency is also the first thing a shape-by-shape build starts to drift on by the third or fourth column.
The one-prompt route: skip the add-in and the shape math
Some teams solve the consistency problem by buying a dedicated Harvey ball add-in: a separate license, a separate icon library, and a separate menu to learn just to keep circles the same size and color. That is a lot of structure for five shapes and a fill percentage. Oria removes the extra step. It is an AI add-in that runs in the PowerPoint task pane and builds a Harvey ball rating grid as native, fully editable shapes on your corporate template in one prompt, so there is nothing extra to install and nothing extra to license.
Because the output is native PowerPoint, every circle stays a real shape afterward. You can nudge one rating up half a level, recolor the accent, or add a row for a new criterion the morning of the review, all inside the same file, without reopening an add-in or reworking the whole grid by hand.

Frequently asked questions
What are Harvey balls used for?
Harvey balls rate several options against the same set of criteria in one glance. A filled-in circle communicates a score, so a reader can scan a whole comparison grid, spot the strongest option in each row, and read the pattern without reading a single number.
How many levels does a Harvey ball scale usually have?
Five levels is standard: empty, a quarter, half, three-quarters, and full, in 25 percent steps. Some grids compress that to three levels, empty, half, and full, when the underlying rating is genuinely that coarse. Going past five levels usually adds precision the reader cannot actually see at a glance.
Can I build Harvey balls in PowerPoint without an add-in?
Yes. The native Pie shape and Unicode circle characters both build a full, consistent Harvey ball set with tools already in PowerPoint. Neither requires installing anything, and both hold up fine in a corporate deck once the fill direction and sizing stay consistent down every row.
Do consultants still use Harvey balls in decks?
Yes. Harvey balls remain a standard way to present a multi-criteria comparison in strategy, finance, and vendor-assessment decks. They compress a wide grid of ratings into a shape a reader can scan in seconds, which is exactly the density these decks need.
What is the fastest way to build a full Harvey ball comparison grid?
Describe the criteria, the options, and the rating for each cell in one prompt to Oria. It builds the grid as native, fully editable PowerPoint shapes on your template directly in the task pane, so you skip drawing and aligning each circle by hand.
