Save UIWebView content as A4 sized PDF - ios

Question

I have gone over previous questions touching upon the subject, but A4 Sized PDF is the troublesome part.
The code I have written below saves a proper (proportional) PDF file, but its size (area wise) is 4 times of A4-Size. If I halve the height and width, I get an A4 sized PDF but the content overflows into two pages.
How do I solve the problem? (fundamentally pertaining to scaling)
-(void)savePDFFromWebView:(UIWebView*)webView fileName:(NSString*)_fileName
{
int height, width, header, sidespace;
height = 1754;
width = 1240;
header = 15;
sidespace = 30;
// set header and footer spaces
UIEdgeInsets pageMargins = UIEdgeInsetsMake(header, sidespace, header, sidespace);
webView.viewPrintFormatter.contentInsets = pageMargins;
UIPrintPageRenderer *renderer = [[UIPrintPageRenderer alloc] init];
[renderer addPrintFormatter:webView.viewPrintFormatter startingAtPageAtIndex:0];
CGSize pageSize = CGSizeMake(width, height);
CGRect printableRect = CGRectMake(pageMargins.left,
pageMargins.top,
pageSize.width - pageMargins.left - pageMargins.right,
pageSize.height - pageMargins.top - pageMargins.bottom);
CGRect paperRect = CGRectMake(0, 0, pageSize.width, pageSize.height);
[renderer setValue:[NSValue valueWithCGRect:paperRect] forKey:#"paperRect"];
[renderer setValue:[NSValue valueWithCGRect:printableRect] forKey:#"printableRect"];
NSData *pdfData = [self printToPDFWithRender:renderer paperRect:paperRect];
// save PDF file
NSString *saveFileName = [NSString stringWithFormat:#"%#%dx%d.pdf", _fileName, (int)pageSize.width, (int)pageSize.height];
NSString *savePath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:saveFileName];
[pdfData writeToFile: savePath atomically: YES];
}
- (NSData*) printToPDFWithRenderer:(UIPrintPageRenderer*)renderer paperRect:(CGRect)paperRect
{
NSMutableData *pdfData = [NSMutableData data];
UIGraphicsBeginPDFContextToData( pdfData, paperRect, nil );
[renderer prepareForDrawingPages: NSMakeRange(0, renderer.numberOfPages)];
CGRect bounds = UIGraphicsGetPDFContextBounds();
for ( int i = 0 ; i < renderer.numberOfPages ; i++ )
{
UIGraphicsBeginPDFPage();
[renderer drawPageAtIndex: i inRect: bounds];
}
UIGraphicsEndPDFContext();
return pdfData;
}

Here paperRect you providing is not of A4 size
CGRect paperRect = CGRectMake(0, 0,595.2,841.8);
According printableRect would change
CGRect printableRect = CGRectMake(sidespace,
header,
pageSize.width - (sidespace*2),
pageSize.height - (header*2));
Also I think no need to specify contentInsets as printableRect will do the same. So remove below lines
UIEdgeInsets pageMargins = UIEdgeInsetsMake(header, sidespace, header, sidespace);
webView.viewPrintFormatter.contentInsets = = pageMargins;
