Setting fixed footer - Why in my case proper min-height is 130px instead of 114px?

<!DOCTYPE html>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Best City Guide</title>
  <link rel="stylesheet" href="css/normalize.css">
    <link rel="stylesheet" href="css/style.css">
  <div class="wrap" >
     <header class="main-header">
     <div class="container">
        <h1 class="name"><a href="#">Best City Guide</a></h1>
        <ul class="main-nav">
          <li><a href="#">ice cream</a></li>
          <li><a href="#">donuts</a></li>
          <li><a href="#">tea</a></li>
          <li><a href="#">coffee</a></li>
    <div class="container">

  box-sizing: border-box;

  padding: 0 1em;

    margin-top: 0;
.main-header {

  background: #3acec2;

.main-footer {
  text-align: center;
  padding: 2em 0;
  background: grey; 

@media (min-width: 700px){
    min-height: calc(100vh - 130px);
      width: 70%;
      max-width: 1000px;
      margin: 0 auto;

As I looked with chrome tools height of footer is 114 and that's value should be substracted from 100vh. How ever that code adds scrollbar-y. Why is that? Only value 130 works properly. I understand that paragraphs inside can cause that(margin: 16px 0;). But I used box-sizing. Thanks for help.

It is necessary to take into account that the tool itself takes up a space (pixel) is probably what is causing the difference of values

By the way, if isnt it please post the correct answer for i can see too

But where did you set min-height of footer to 114 or where did you get these numbers? The only thing I see now it top and bottom padding of 2ems.
