NSLayoutManager *layoutManager = [[self textView] layoutManager];
    NSTextContainer *container = [[self textView] textContainer];
    [layoutManager ensureLayoutForTextContainer:container];
    CGRect rect = [layoutManager usedRectForTextContainer:container];

    UIEdgeInsets insets = [[self textView] textContainerInset];
    height += insets.top;
    height += insets.bottom;
    height = ceilf(height);
    return CGSizeMake(320, height + 16);  // 16 comes from the current top and bottom cell padding.
