0:00Rounded corners in Tableau.

0:02It's about time and there's one part of this feature I really take issue with, but we'll cover that later on.

0:07First, let me just show you how it works.

0:09I've opened up Superstore, very simple workbook.

0:12You've all got it as a default workbook.

0:14If you click on the sheet that you'd like to apply a rounded corners to, you'll see there's a new option called corner radius.

0:20Now you might not see this inner padding option.

0:22It's super important that you have it.

0:24your window might have opened something like this.

0:26I don't know why that happens, but just make sure you expand this item hierarchy down so that that is the case.

0:32So now you can see all three options that you really need.

0:35Outer padding and inner padding have always been there, but they're actually super important for this feature to work well.

0:41Let me go ahead and show you why.

0:44Outer padding applies to the outside of the object, but you can't really see it working unless I give the background a color.

0:50So let me go ahead and set it to something bold, let's choose pink in this particular case

0:55Now that we have that color, you might look at the sheet and think, well, it's only applied it to the top.

0:59However, that's actually incorrect because there's one weird thing about sheets.

1:03in Tableau, when you apply a color to the background, the chart itself does not inherit that background.

1:08So what you have to do to see that background is actually add inner padding.

1:12Inner padding applies to the container of the chart but not the chart itself

1:16So let's go ahead and set that to 10 and you'll see that that color now goes all the way around.

1:22That's what I mean.

1:23You apply the colour to the background, but the background does not apply to the chart, even though the chart is the only thing in the sheet.

1:29I never know why it was designed that way.

1:31That's just the way it is.

1:32But now that that's happened, if we go in and start applying a corner radius, let's go ahead and pick 10.

1:38You'll see that we start to see something, a very, very small clue here

1:42If I click out, you'll see ah there we go.

1:44This corner has a radius of 10.

1:46So it is working, but there's something that feels off.

1:49Let's go ahead and select the sheet again.

1:51And now this is where outer padding comes in because

1:54Corner radius applies between the space between outer and inner padding.

1:58Outer padding applies to the outside of the object, inner padding applies to the object itself, except for the sheet.

2:04So now you understand why those two things are important.

2:08The downside of this though is that something still feels off.

2:10You see, when people think about this feature, what they really want is for the chart itself to have those rounded corners.

2:15So you see this chart still has flat edges and it really doesn't quite work.

2:19So you have to get smart with how you apply this.

2:21So rather than applying the background color to the sheet itself, you need to do it elsewhere.

2:25So let's go ahead and set that to none.

2:28Let's go back, click out of this, and go to dashboard and let's go format.

2:32And then we're going to set the same color.

2:34to the whole entire dashboard.

2:35So now you see the whole dashboard has this color.

2:38Go back to the object, come out of the dashboard formatting capability, and then what we can do now is set the outer padding to zero.

2:46and give the chart itself a nice white background and now that round of corner sits a little bit nicer.

2:53Now we could give that

2:55chart a little bit more breathing room.

2:57So let's do this.

2:57Let's exchange the padding a little bit.

3:00Let's actually put it all on the outside.

3:02Let's put five pixels around the outside.

3:05That sort of hugs the chart but it's not too tight

3:07I I don't want to use an uneven number, so let's say eight.

3:11Well that still doesn't work well.

3:12Let's just go with ten.

3:14That kind of works with the scenario that we're in.

3:16And now you see that uh rounded corner looks like it applies to the chart.

3:21So just by changing the background, inner and outer padding, you really, really master this.

3:26In earnest, this is my real issue with this feature.

3:28You know, people when they look at this, they don't think that the sheet itself and the chart itself is separate.

3:33Yet that's the only thing we have the ability to add this rounded quantity.

3:36So an enhancement I'd recommend to Tableau.

3:38is apply this properly, let it apply to the chart and the object of the chart, or give us a way of controlling those two things separately.

3:46I can't do it in the sheet.

3:47And yeah, having to play around with these colours really does still constrain my options.

3:51But nevertheless, happy to have rounded corners because what people were doing instead was in my opinion ten times worse.

3:56hacks of all kind just to get rounded corners and images making our dashboards much much bigger and more blated with images themselves anyway that's pretty much it for this feature thanks for watching I'll see you in the next one

Tableau's new corner radius option lets you round the edges of a sheet, but it only rounds the sheet container, not the chart inside it — so to get the effect people actually want, you need to control background colour and padding carefully.

Using a simple workbook, Tim shows the new corner radius setting on a sheet and walks through why the default result looks wrong until you understand how padding and background colour interact.

The Breakdown
  1. Find corner radius on a sheet 0:01

    Click on a sheet and you'll see a new corner radius option alongside outer and inner padding. If inner padding isn't visible, expand the item hierarchy in the formatting pane to reveal all three options.

  2. Understand outer vs inner padding 0:42

    Outer padding affects the space outside the object; inner padding affects the container around the chart. You need both visible and understood before corner radius will make sense.

  3. Know the sheet/chart background quirk 1:04

    A background colour applied to a sheet does not automatically apply to the chart inside it, even though the chart is the only thing on the sheet. You must add inner padding to actually see that background colour show through around the chart.

  4. Corner radius applies between outer and inner padding 1:42

    Setting a corner radius rounds the space between the outer and inner padding boundaries, not the chart itself. This is why the rounding looks like it's only partially working until you set both paddings correctly.

  5. Move the background colour to the dashboard 2:22

    Because the chart itself won't inherit rounded corners this way, don't colour the sheet background. Instead set the sheet background to none, apply your colour at the dashboard level, then set outer padding on the object to zero and give the chart a contrasting background (e.g. white).

  6. Fine-tune padding for a natural look 2:47

    With the dashboard coloured and outer padding at zero, add a small amount of outer padding back (Tim settles on around 10 pixels) so the chart has breathing room without looking too tight — adjust to taste rather than following an exact number.

  7. Recognise the feature's real limitation 3:21

    There's no way to apply rounded corners to the chart and its container independently — you can only round the sheet-level object, which forces this workaround with background colours and padding rather than a direct setting.

Worth Knowing
  • Inner padding may not show by default in the formatting pane — you have to expand the item hierarchy to see it.
  • A background colour set on a sheet won't show around the chart unless you also add inner padding, which is not obvious.
  • Corner radius rounds the space between outer and inner padding, not the chart itself, so it can look like it's not working at first.
  • Tim flags this as a design gap he'd like fixed — ideally Tableau would let you control chart and object rounding separately.
Use It When

Reach for this when you want dashboards with rounded corners instead of the older workarounds people used, like faking rounded edges with images, which bloat the workbook.
