Which is it? – Homer Jan 8, 2016 at 21:27 @Homer one is bytes and the other is kilobytes. The value is specified in kB so you should use 2097151 – Ramón May 2, 2016 at 23:06 @Homer the accepted answer only states the maximum value of the int type, where as IIS accepts this as the maximum value. – ywm Jul 6, 2016 at 10:39

<system.web>
    <httpRuntime maxRequestLength="2097152" requestLengthDiskThreshold="2097152" executionTimeout="240"/>
</system.web>
<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="2147483648" />
        </requestFiltering>
    </security>
</system.webServer>
                If I am not wrong the maxRequestLength is in bytes. So the max value should be also 2147483648

UPDATE
As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295
                Equivalent of your value would be 2,097,152 (kB), which is out of range by 1. The maximum value is 2,097,151 (kB) i.e. 2,147,482,624 bytes.

                Int32.MaxValue is 2,147,483,647. I didn't make this number up. If you doubt me, open up PowerShell and type [int]::maxvalue and see what you get.

                Have you tried to set maxRequestLength to 2,147,483,647 or 2,097,152? You'll get a Configuration Error. That's why your answer is incorrect and I comment on it. [int]::maxvalue is not in an allowed range.

                I've test maxRequestLength = 2147483648 and did not receive an error for IIS 7.5. Mark is correct. Perhaps it is different for IIS 6?
