Align a circular border

Question

I am having difficulty aligning my circular border to the text above it, and centering the text within the circle. When I comment out the width: 80px; in my .oval class then it appears to be aligned however the circle is then distorted

<div class="container body-content">
    <div class="row tab-content">
        <div class="jumbotron">
            <h1>Welcome, Admin</h1>
            <p class="lead">Please select one of the tabs above to begin</p>
        </div>
        <div class="row adminrow">
            <div class="col-xs-2 col-xs-offset-1">
                <h4>Total Users</h4>
                <div class="oval">
                    <h4>100</h4>
                </div>
            </div>
            <div class="col-xs-2">
                <h4>Unauthorized Users</h4>
                <div class="oval">
                    <h4>25</h4>
                </div>
            </div>
            <div class="col-xs-2">
                <h4>Total Games</h4>
                <div class="oval">
                    <h4>0</h4>
                </div>
            </div>
            <div class="col-xs-2">
                <h4>Games Played</h4>
                <div class="oval">
                    <h4>80</h4>
                </div>
            </div>
            <div class="col-xs-2">
                <h4>Investigator Groups</h4>
                <div class="oval">
                    <h4>2</h4>
                </div>
            </div>
        </div>
    </div>
</div>

My CSS class is as follows

.tab-content {
    border-left: 1px solid #ddd;
    border-right: 1px solid #ddd;
    border-bottom: 1px solid #ddd;
    padding: 30px;
}

.jumbotron {
    text-align: center;
}

.adminrow {
    text-align: center;
}

.oval {
    width: 80px;
    height: 80px;
    border-radius: 50%;
    background: #000000;
    color: white;
    text-align: center;
}

Answer 1

you just need to change the display property of circle:

{
    border-radius: 50%;
    display: block;
    width: 80px;
    line-height: 80px;
    text-align: center;
    // other properties
}

Answer 2

Would adding this do what you want ?

.oval {
    line-height: 80px;
}
