Your fingers are hovering over the keyboard, ready to type in those numbers. But wait&mdash;do you have all the information you need?

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">Plugging in the wrong numbers is just as bad as guessing. Actually, it might be worse&mdash;because you'll think you're right until that delivery truck shows up with way too much or way too little.

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">Before you calculate, ask yourself these five questions. They'll save you from a world of hurt.

<li>
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">For a driveway:</span> If you're driving cars on it, you need <span style="font-weight: 600;">4-6 inches</span> minimum. Trucks or RVs? Go 6-8 inches.

</li>
<li style="margin-top: 6px;">
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">For a walkway:</span> 2-3 inches is plenty. Any deeper and you're just wasting money.

<li style="margin-top: 6px;">
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">For decorative beds:</span> 2 inches is usually enough. The gravel just needs to cover the fabric and look pretty.

<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">For a base layer under pavers:</span> You might only need 1 inch of gravel as a setting bed&mdash;check your paver instructions!

Thin gravel shifts, ruts, and exposes fabric. Thick gravel stays put.

Calculate each one separately, then add them together. A gravel calculator can handle multiple areas&mdash;just don't try to fudge a weird shape into one rectangle. You'll be wrong.

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">Here's a fact that surprises most DIYers: <span style="font-weight: 600;">Gravel compacts.</span>

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">When you drive on it, walk on it, or run a plate compactor over it, those stones settle together. That 4-inch layer you spread will become closer to 3.5 inches after compaction.

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;"><span style="font-weight: 600;">The rule:</span> Always add 5-10% to your calculation to account for settling. If your calculator doesn't have a "compaction factor" setting, just multiply your final number by 1.05 or 1.1.

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">Better to have a little extra than to come up short.

But if you're putting down a base layer of #3 rock first, then a top layer of #57, you need to calculate each layer separately.

<p class="ds-markdown-paragraph" style="margin: 16px 0px; color: #0f1115; font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif; font-size: 16px;">Also, if you're adding to existing gravel, measure how deep the old stuff is so you know how much new stone to add.

<li>
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">If your calculation says 1.2 yards, order 1.5.</span> You can't order 0.2 yards from most places anyway, and extra gravel is useful for filling low spots later.

</li>
<li style="margin-top: 6px;">
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">If you're between sizes, go up.</span> Running out mid-project is a nightmare. Having a small pile left over is a minor inconvenience.

</li>
<li style="margin-top: 6px;">
<p class="ds-markdown-paragraph" style="margin: 0px !important 0px 0px 0px;"><span style="font-weight: 600;">If your supplier only delivers full yards,</span> round up to the next whole number. Paying for 2 yards when you need 1.2 is better than paying for 1 and coming up short.
